Optimizing For Bandwidth On Apache And Nginx
Dec 17, 2014We'd like to use this tool from Google on our Plesk server: [URL]
is it useful getting these tools going on server, and are they worth it?

Optimizing Apache
Jun 27, 2008I have a server facing to 150+ requests/sec. Using apache 1.3.39. The current config here
Timeout 15
KeepAlive Off
MaxKeepAliveRequests 10
KeepAliveTimeout 5
MinSpareServers 15
MaxSpareServers 20
StartServers 15
MaxClients 400
MaxRequestsPerChild 100000
I wonder if I can change anything to make site is faster? Currently, it's very slow. It's one core2duo box with 2GB RAM

Apache Goes Down + Optimizing Dedicated Server
Oct 4, 2007I am having problems with apache going down at least once a day. In Plesk there is a watchdog that monitors the service and then restarts it, but tries 5 times and fails, so apache will still be down and monitoring released. I really don't know what is causing this problem, maybe I could get some help? (Server specs at bottom of post, hope this is all you need)
error_log shows:

Nginx Works With Apache
Aug 14, 2008I am doing my web like this:
1) nginx listening at port 80
2) apache listening at port 78
3) nginx throws all shtml pages to apache
they are working perfectly, except one small thing:
I don't want any public visitor may visit port 78 directly, for now, both:
[url]
[url]
are working for visitors.
Anybody knows how to block/hide port 78 to the public access?
my nginx config snippet:
Code:
location = /index.shtml {
proxy_pass [url]
}
my apache2 config snippet:
Code:
Listen 78
If I make apache as follows:
Code:
Listen 127.0.0.1:78
I will get 502 bad gateway when I visit:

Convert Apache To Nginx
Apr 13, 2015I am wondering if there is an easy way to convert apache to nginx on my Plesk 12 server. Ideally, I would like to save all my hosts without having to re set them all up. I have been searching online, but haven't found a simple way to do so.

I have -
On a common shared environment, I started off with Apache - was fine until some load started generating and it became crapache.
Then litespeed - Totally awesome, could seriously feel the difference, but its cost is something not everybody can afford.
Then nginx - Very nice, felt like litespeed only, the only difference was it got quite complex in configuring it at a later stage BUT its free'ness made me love it badly.

Nginx is already installed, what I need is a workable configuration file for nginx so that it serves all static stuff (images and a few folders with static html) and instructions in how to create it. The server is running DirectAdmin panel, Apache 2.24, PHP 5.23 and XCache 1.2.

Optimizing A VPS Server
Sep 6, 2008A friend of mine has a VPS server from godaddy, the site he is hosting on this VPS is quite slow and times out a lot.

If you would recommend the third option, it would be great if you can let me know about companies that provide this service.

Nov 2, 2009I optimized a mysql table of 2 million records and about 500MB.. it took about 15 minutes.. However, on the same DB now i have another huge table of 88 million records, it size is 2.2 GB and it has about 30 MB to optimize... my questions..
1.- How can I speed up the optimization process so it can take the less possible time? any tweaks to my.cnf?
2.- Should I repair it using phpmyadmin or just from the shell?
3.- Should I stop http traffic during this optimization?

Optimizing Server For Proxy Hosting
Mar 21, 2007i have a Pentium D 820, 2GB Ram at LT where i am hosting a few proxies. Using Centos and Directadmin.
It's realy fast and i am happy with it. The only problem i am facing is that load is jumping up to 60 sometimes but just for a few seconds. Especially when a lot of people are using the proxy and it slows down a bit. That affects only the proxified pages and not a few personal html sites i also host there.
At the moment i am seeing in top that the CPU usage varies from 0,2 to 8, 12, 21 etc but just for a second or two
here is the top output
Quote:
[root@server ~]# top
top - 12:46:18 up 23 days, 2:36, 1 user, load average: 0.36, 0.44, 0.29

and the number of connections on port 80

[root@server ~]#
is there any way to tweak or optimize the server so than it can cope better when a lot of people are using the proxy.
Optimizing Lighttpd For Large Files (180mb Avg)
May 9, 2008I 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.

Jul 7, 2008I am running a SQL test server here that is piping HUGE amounts of data for a test project I am running.
Approximately 30 queries a second - constantly. That's over 2.5M queries a day -- so we are talking big (I think?)
I am currently running this test on a
AMD Phenom 9300, 4GB RAM - SATA 500GB HDD and I am running MySQL 5.0.51a i386 on CentOS
I have programmed a process control for our applications purpose - basically it controls the launching of our SQL intense applications, and stops launching when the Load is greater than 2.5
I have plans to optimize the number of queries (I will build in a cache to some of the applications - and run INSERT statements all together) however I am looking for SQL tweaks that will improve performance. Would running the 64bit version work better?
Optimizing MySQL On A Busy Server (4 Gigs Of Ram)
Dec 8, 2008it's getting to the point where I need to optimize MySQL to better handle a busy server.
These days it seems MySQL is using 30% - 60% CPU almost constantly. But, the good news is that I've got 4 gigs of ram on this box and their seems to be an access of 600mb free constantly throughout the day.
Is it possible to tweak MySQL to a little more RAM dependent and take some of the load off the CPU? It seems MySQL wont go over 300mb of ram at any given time.. I'm already working on optimizing the SQL Querys on the web page itself.

Optimizing These Particular MySQL Slow Queries In WordPress
Jun 14, 2008What I did here was create /var/log/mysqld.slow.log for queries that are taking one second or longer. After around 36 hours, here is what I came up with. Since the file size of /var/log/mysqld.slow.log was 219KB, posting it in its entirety it not practical. Therefore, I used a program, the perl script known as mysql_slow_log_parser found on www.retards.org, to parse the mysqld.slow.log to make it easier to interpret and read. The result was that the original filesize of 219KB was converted to the smaller size of 14KB....
