Performance Testing, Pre-site Launch
Jan 23, 2007
We're in the midst of re-developing our website, and have become concerned that the servers and CMS we have put together may not be able to cope with the traffic we get.
Our current site doesn't get an enormous amount of traffic but in using the in-development site it seems to be a little slower than we'd like.
I have put together an RFP to solicit help in performance testing, and before I post it on the sitepoint marketplace I thought I'd see what people here thought about this sort of testing. If you have any experience with it and advice I'd love to hear about it.

I am writing a financial statement for my business plan and like to know what numbers should I expect from the the host. If the potential traffic will reach 405,000 visitors a month what my requirements for the hosting company should be?

So yesterday my team completed our website. Everything uploaded perfectly and works without a hitch except send mail.
When someone registers on our forum or registers on the main site they are send an e-mail validation, standard procedure. However the e-mails do not get through!
It looks like every email provider is filtering out some part of the email. I don't know whether it's the domain, ip, subject/message contents. Please take a look for yourself. We are using an offshore server in the Netherlands. The only email provider that would even accept our e-mails so far has been Gmail and Gmail automatically thought it was spam.
We have tried our scripts on a US host (1and1.com) and they e-mail to any email provider no problem. So I don't know for sure what's going on. Unfortunately I am about to get rid of 1and1 so I can't use them permanently.
Here are the contents of our failed email: ...

Is there a site which will enable me to enter url of my website and it will simulate visitors from multiple locations. It needs to open the page completely, and run for example 10 minutes. Two things I found are host-tracker, but it just gets headers from multiple locations, and does it only once. Another thing is Paessler software which can test exactly what I want (number of visitors for some period of time with full page download) but it must be run from one (my) PC, so I can not test bandwidth from multiple locations. I need combination of these two, anyone knows for something like that on the net?

I'm not sure if i posted this in the right place - but couldn't find a better place. Here is my problem.
I am converting my current site [URL] ... from one software to another. I am testing it on a temporary domain name [URL] .....
Once i finish testing i want to move the .co site to the .com site and i don't know the best way to do this.
An obvious way would be to move all of the files and databases to the .com site after first deleting all of the files at the .com site. I would also have to do a few tweaks to the software to make sure it's pointing to the .com and not .co where iI tested.
but this method seems clunky.
Is there a way to just point the .com to the .co when I'm ready to 'move' and therefore nothing would actually get 'moved'?? both the .com and .co are on the same VPS.

I will be launching a new LAMP Web App that is a social network. At this point we have been testing on a Dreamhost shared hosting plan. However, we will be launching soon and I don't expect massive adoption I expect it to be slow and steady. 5-20 new signups a day.
I want to ensure that even my first users experience a fast site, and I am wondering If I moved to a 256 or 512ram VPS will they notice a speed difference even with no real load?
I am bootstrapping so money is tight and if I can hold off a few months I would do that if there would be no perceivable performance difference.
Does anyone have any stories of moving from shared to vps before launching and noticing major page load time reductions?

have been handed a project to migrate a web page from our old Oracle OAS 10G server to a Oracle Weblogic llg server.
This page is manually deployed along with the web folder from a third-party Automic Applications Manager (formerly Appworx).
We are not using the default Apache server that ships with the product due to all the paperwork and configuration required to deploy it in a secure environment.
The old configuration is already approved to allow connection via our Oracle (Apache) webservers.
I can launch the page fine but when I call the .jsp file to launch it it opens the file instead of launching it (Windows 2008 server).
I've associated the file types, jsp and jnlp to javaws.exe. I found a reference in the old httpd.conf file and added this to the new httpd.conf file on the weblogic server. I also dug into the default install and found the same line. I've bounced the ohs to source this and it still opens instead of launches. How do I change this behavior?

I am using dreamhost host 3 of my web sites and 1 blog. Dreamhost is great, offers alot space and bandwidth.
but I think they are oversellling their space, sometimes it gets really slow. (overselling ? ok, I dont really know, but sometimes its really slow, and most my asian readers said need to refresh to load the page. I am wondering if theres a way to check if they are overselling or not.)
I am thinking about buying vps, even tho, I still got 5 month left with dreamhost.
I found 2 vps companies are highly recommanded on this forum, JaguarPC and LiquidWeb.
theres already a post compared both companies in terms of price and service. I say I will pick JagarPc, cuz, its basic plan just 20 USD, and htey got promotion now, its even cheaper. and basic Liquidweb vps plan is 60 bucks.
I am wondering why Jagarpc is so cheap , are they overselling? how can we check if they are overselling.
I found a few posts saying how good jaguarPc is. and they are not overselling, but those members just signed up this month, and only have 1-3 posts. I cannot really trust those new members.
Can someone share their experience with JaguarPC? compare JaguarPc performance and liquidweb performance. antoher question is switch from dreamhost to JaguarPC basic vPS plan, will performance gets better?
last question: VPS account allows 3 IP, 3ip = 3 domains? if not, how many domains can I have?

I am migrating my website to Hostgator, and before I change the DNS entries, I want to make sure that everything displays properly. To do this, I have added an entry into my /etc/hosts file pointing the domain to the new host. If I then ping the domain, the reply comes from the correct IP address. However, if I try to view the website, it is still served by the old host.
I thought it might be a caching issue, but I have checked with wireshark and using curl, and it is definitely connecting to the new IP address, but the server that is returning the pages is still the old one. I've contacted hostgator support, but when they make the changes to their hosts file, it loads correctly. Is this a local problem (my system), or something with their server configuration?

I am looking for some decent tools to test a web server that can run large scale web sites running Windows and Linux.
I am more interested in the underlying hardware at this point to see if the servers them selves are capable of withstanding the loads without choking.
I am most interested in Disk testing and Network testing but the server but of course the server as a whole is important to since cpu and memory bottle neck can affect everything.

I am currently developing a piece of software that will act as an all purpose control panel for a specific niche. I have coded the vast majority of the control panel already, and want to purchase a cheap (under $25/mo) VPS to test the installation and performance of the control panel.
As a result of me testing various configurations the main feature I am looking for is free (or very cheap) OS reloads.
I want to be working under a CentOS environment, and have a decent amount of CPU that I can use. Disk space and bandwidth are really not an issue, as I am simply testing using this VPS to test the software I am developing.

for testing reboots? Basically, the goal is to avoid having a reboot fail leading to support or reinstall costs.
Right now, I'm using qemu -snapshot /dev/hda, but that obviously has limitations.

I have 2 questions here.
1. I have installed mod_evasive version 1.10.1 on a Cent OS 4.4 server.
I'm using the test.pl script that comes with mod_evasive to test the configuration and when running the script from the same server mod_Evasive is installed. The mod_evasive is able to detect the intrusion and block the IP of the server.
If I use the same test.pl script from an external server the requests come in and are viewable in the access log but mod_evasive doesnt block the IP of the external server. Probably is not blocing the ip of the external server because of latency.
Is there a way to modify the test.pl script to make it more agressive and get results when testing from an external server?
Here I'm pasting the code of the test.pl script:
Code:
#!/usr/bin/perl
# test.pl: small script to test mod_dosevasive's effectiveness
use IO::Socket;
use strict;
for(0..100) {
my($response);
my($SOCKET) = new IO::Socket::INET( Proto => "tcp",
PeerAddr=> "test.domain.tld:80");
if (! defined $SOCKET) { die $!; }
print $SOCKET "GET /?$_ HTTP/1.0
";
$response = <$SOCKET>;
print $response;
close($SOCKET);
}
2. Also, I have sendmail installed and on the mod_evasive config I have email address specified on DOSEmailNotify. When testing from the internal server with the test.pl script the server is able to block the ip, put in the hash table but it never sends an email to my email address.

I just installed Mod Evasive and I want to fully test it but dont know how. I was planning to use Http Traffic Generator from NsaSoft but I'm afraid the ISP will block my IP space after testing the web site.
What will be the best tool and way to test this module?

We have been doing some research on some colocation facilities lately and a question came up about load testing. I'm wondering what the standard is in regards to load testing a colocation facility.
Are they full load tests? How often are they done? How long are those tests done for?

I've installed a certificate in my server that's certified by a CA, but I want to see what happens when that CA is no longer listed as trusted. In Internet Explorer I click Advanced and de-select "Server Authentication" for my CA. When I go to my site, though, I don't see the usual untrusted warning come up. How do you test this?
what's the difference between the certification authority and publisher sections in Internet Explorer?

I want to know if there is a set of tools or a linux distro that I can use to create several Virtual Machines and make them use up all their allocated Memory/CPU to the max to see how much the VPS Node will hold.
I do this on Windows easily as I overclock my PC at home. But in linux, no idea. I need something that will do iterations like Prime95 or SuperPI.

I have a USB drive with Uniserver, XAMP, and WOS portable webservers installed.
The problem is that I would like to have a "test" directory that is independent of these three servers, but still accessible by typing something like "localhost/test" into the browser, regardless of which package I'm running.
Each server package has its own neat little pros and cons and I'd like to be able to play around with all of them and still have the same common access to the same test directory.

Currently working on securing my server and i think I'm doing quite well until I asked myself the question, have I done it right? Is there anyway to actually test how secure my server actually is? I'd rather not just wait and see if someone can hack me to bring to light what I did wrong...I was also thinking of hiring someone to secure my server but then how do I know that they've done anything different to me?
Are there any scripts or programs I can run to test server security?

I've been playing with hyperVM lately and was wondering what tools all you computer geeks use to stress test your VPSes.
Right now I'm testing out Xen VPSes, Linux AND Windows.
Can some people recommend some tools to stress test reliability of the VPSes on both linux and windows?
Windows seems a little flaky to me on Xen unless I'm doing something wrong.
Stress tests based on a hosting environment would be perfect.

I'm moving from my old XP PC to a new PC with Vista (a mistake, but that's a different story).
I'm trying to set up some sites in IIS so that I can develop locally without having to publish to a remote web server.
I've installed IIS7 from the control panel, and am now looking to set up my first site. I've put the site name in, and the path to the site on the computer, but I'm getting an error in the 'bindings' section. I've left all of this empty because I don't know what it means (it didn't ask for any of this in IIS on XP) but when I try to add the site it gives me the following error:
"The binding '*:80:' is assigned to another site. If you assign the same binding to this site, you will only be able to start one of the sites. Are you sure that you want to add this duplicate binding?"
Does anyone know what to do here? I'll need to add about 100 domains to IIS so I want them all to be accessible locally. How do I do this?

I've recently setup a vps with cPanel DNS only - to provide more redundancy to my hosting/dns network. (secondary dns solution)
I've set it up so my hosting server synchronises changes on the vps as well.
Since I can't actually get it to list the dns records on the vps via whm, how I can check that the records are on the vps and can be queried correctly.
When I tell it to manually synchronise the records from my hosting server, it reloads bind on both servers with no errors.

how you test your provider's network. What things do you look for? I hear terms like latency, and I see people posting their trace routes, but I just don't know what information you are trying to obtain from these tests. What other tests do you run, and what are you looking for?

We have recently moved to a new datacenter and I was wondering if anyone on these forums could provide their experiences with "real-world" testing.
Upon move-in, we had a few issues. Obviously now the executives in the organization I work for are looking for justification for moving to the new colo.
software, or an online service that will stress test our current setup? Obviously I have MRTG, Awstats, and a few other of the most well known polling packages installed and working correctly, but what does everyone else use for stress testing?

I'm running a Fedora box and am getting these kinds of messages in /var/log/messages:
Oct 26 13:41:20 tx kernel: Unable to handle kernel NULL pointer dereference at virtual address 0000000c
I have a feeling this is a memory error and am looking for a way to confirm this.
I found a package called memtest86+ (via yum) but have never used it. Have any of you used this program in the past and if so what are the steps? Does the server have to be shut down? Are there other programs out there to accomplish what I am trying to do?

I am trying to migrate from desktop anti spam to a server antispam solution (using Exchange 2003 Enterprise)
I do not want to give out names, but I tried one solution from a advertised company and it put my mail throughput down to one message every ~3 seconds which built up a ever growing queue.
The reason I beleive is that DNS lookup was trying for each message in turn instead of running simultaniously which slowed it down.
Anyway, I am basically looking for a mail bomb with statistics!
I want to be able to instantly send ~50 messages to my smtp server, and see how long it takes to get through the queue.
