So I've recently ordered a Supermicro 4U server with 24x1TB HDs, 64GB RAM and put it in RAID 10. I'm running Debian 5.0 and have installed lighttpd. All the content I serve are video files (AVi, MP4, MKV, OGM) and each file is about 100-500mb in size. I'm wondering how can I optimize lighttpd to get the best performance out of it. I look forward to your replies.
View 14 RepliesI have four servers with a quad xeon, 4gb ram, and 2x300GB SAS 15K RAID0 harddrives, pushing a total of 1.6gbits. It serves a lot of zip files with an average flesize of 180mb. My question is, how can I optimize lighttpd 1.4.19 to push its max with very low IO-wait. I've looked up some stuff and only found options that deal with lighttpd 1.5 and use Linux-AIO for the backend network. Currently I use writev with 16 workers and an read/write idle timeout of 10s. Logging is off, too.

I can access all the files without any issue.
Until today when I check the flv file on other machine,
[url]
It say 404 no found!
I can access other *.jpg *.html file without any problem, but no flv file.
I thought it's firewall issue, but even I turn off firewall, it's still having the same issue.
And I have another computer in the same network, it's fine. they are all windows XP.
we are running a file sharing service and use lighttpd as a web server
the problem is that in Internet Explorer are some files i.e. .mpg, .pdf
and others opened directly in the browser
so is there a way to prevent this behavior(to force the browser to
download the file) by setting headers (or something else) in
lighttpd.conf?
Any one manage file hosting servers here?
I run file sharing service, bandwidth usage is going up too much, 300 Mbps, anyone know if file hosting sites use bandwidth shaping ? Any recommended settings for lighttpd?
My client's website needs to hold files that are around 60 or 70 MB. The host only allows files up to 10 MB. Is that typical?
Right now I'm linking to a file storage but would rather make the files available from my site without going to a 3rd Party Site. He doesn't want to zip his files either - just to be a straight download.
I have a situation here.
I wanted to transfer a file (about 10GB) from one server to another server. Both server are on the same LAN.
Inside server1, I zipped a folder as file.tar.gz
From server2, I uses wget http://server1.com/file.tar.gz and it says "404 Not Found"
I suspect it won't allow me to download because the file is too big.
Can anyone tell me the format of SCP command for transfering an 18gig TAR.GZ file from one srever to another
say im logged in to the old host via SSH and the backup is located at /home/public_html/cpbackup/blahblah.tar.gz
what command would i put down to transfer to the new server
I have been trying quite unsuccessfully to import a large sql db file via phpMyAdmin for one of my clients. Since the db file is about 250mb I get a server timeout error.how I can do this via SSH...I have a CentOS server 6.5, 64 bit that runs Plesk v 12.0.18

I would like to be able to offer up to 2Gb storage space for 100s, maybe up to a few 1000 users - any solution should scale well. The files would be static files that might be up to 400Mb in size.
It would be nice to be able to give users FTP access to their disk space, although it's not a core requirement.
Knowing Qoodaa was quite by chance.
A few days ago, my friends studying in America recommended me a new popular transfer toolQoodaa. And he told me that it was a quite good software to download files and movies. At first,I was skeptical, but after using it, I found its a good choice to choose Qoodaa. And I have summarized the some features of Qoodaa:
1.Its speed is faster than any other softwares I used before to upload movies.
2.It can download files quickly through downloading links, in a word, it is time-saver and with high efficiency.
3.No limit of space.No matter where you are, it can download fast.
4. Qoodaa is a green software with high security and easy use.
It really can give you unexpected surprise.

I'm currently running on a VPS. My site allows for large file uploads and downloads, with files over 600mb in size.
The server has issues when the site gets three or more requests for large file downloads. I'm trying to grow this site to thousands of users and it is hard to do when the site can't handle even three.
I've been told by my host that I need to upgrade to dedicated. My VPS only has 512mb RAM and one large file download is eating up that RAM. This is causing the issue.
I'm a newbie and while I knew I was risking a bit by going with VPS I do find it a bit annoying that these guys advertise 1TB of bandwidth per month but I can't even support downloading 1GB at the same time....maybe it's just me...
Anyway, I am now looking into moving the large files and the upload/download over to Amazon S3. If I do this I am expecting my RAM usage on the VPS to greatly decrease. Is this correct? If my PHP code is running on the VPS, but the actual file download via HTTP is coming from S3, that should not be a heavy load on my box, correct?
any opinions on S3?

my server has some forums on it,
and it need mysql with php to run,
i want to optimize the mysql to get better performance,
how can i check it my setting is ok and how can i do?
i have two servers behind certain switch,
the two servers are with low load,
but the one is good response,and another one is slow,
i try to restart the httpd,the problem is here still,

I have purchased "Due2Core" with 4GB Ram. i have one problem. i hope someone help me in this matter.
I have hosted only 4 or 5 websites on dedicated. mostly maximum 8000 users visit my website. Maximum B/W usage is 35GB.
Daily 25 or 30 mints my websites "WebPages open speed slow". Some time problem occur for 1 time or 2 times. when i checked my server status report Load only 0.50% and Memory usage 35% only.
when i checked server and my sql usage report maximum http load come from my top visit websites.
some friend suggest me for optimize your dedicated apache. because some thing wrong in your apache.
because i have enough memory.
Anybody suggest me suitable apache Optimization method. with step by step.
Remember, in this time my server run default sitting.
Saw a few mention of optimizing mysql. Sounds like it will help with performance. What exactly is this and will my web host do this for us?
View 3 Replies View RelatedI recently got my first dedicated server and now have it all up and running. I would like to optimize mySQL for improved performance.

to optimize mysql for my server. What would the cost be?
View 14 Replies View RelatedI've been a long time follower of wht.com from reading the hosting reviews to optimizations, and now it's come to that point that I need to post a question to get more accurate help than reading others configurations since all servers and sites have their needs. So here it goes.
Server specs:
Ubuntu dapper
Apache 2.2.4
PHP 5.2.3 - eaccelerator 0.9.5.1
mysql 5.0.22
2.6.15-28-server #1 SMP i686 GNU/Linux
cpu: Intel Xeon-Clovertown 5320-QuadCore 1.86GHz
ram: 2x2GB
As I wrote in the topic my main concern is my apache config. I've tried many many different configs but I'm never sure when to stop optimizing it.
The site is a chat community (myspace like site) with over 1000-2000 simultaneous users online that do everything from posting images, to talk in the forums. And yes I host everything on the same server atm.
My worry is that at night when the site has the most visitors the amount of processes that get produced get 'cut' as it seems to reach a limit somewhere. Below is an image of cacti with load and processes. Please ignore the load peaks as they are nothing then my average 'testing' periods of new functions
[url]
This seems to be run by my Max/MinSpareServers which I've played around with but as I said never could find a perfect spot. The amount of processes have always been controled by these values, before I increased them a couple of days ago the amount was around 600 processes to the max. Now as you can see on the latest graph it's around 800.
I've tried the default values but the site went to slow with those values. I've lately come up to what I think is insane values but it keeps the server ticking in a nice pace.
So I'm asking you guys for help as I've reached my trial and error sessions. I have no clue what 'ok' values are for amount of current processes running, and I don't' feel confident to increase the values.
here is my apache config.
Timeout 60
KeepAlive On
MaxKeepAliveRequests 3500
KeepAliveTimeout 2
StartServers 190
MinSpareServers 170
MaxSpareServers 230
ServerLimit 700
MaxClients 700
MaxRequestsPerChild 6000
My server: Opteron 165 + 2GB RAM, running CentOS
I have noticed that if I enable KeepAlive, the performance is much more better. However, Apache will be frozen few times a day without any reason. So, I need to turn off KeepAlive. Is there any idea why and how to fix? This is the configuration
Timeout 300
KeepAlive On
MaxKeepAliveRequests 10
KeepAliveTimeout 2
MinSpareServers 10
MaxSpareServers 25
StartServers 15
MaxClients 250
MaxRequestsPerChild 10
I bought a new server to run proxy websites on it.
how to optimize my apache.
There are some great tools to optimize MySQL, however I have not been able to find the equivalent for Apache + PHP. I have a lot of experience tweaking these two in extreme traffic environments, but there is no beating a program that can simultaneously evaluate several inputs over time to calculate optimal settings.
