What settings for maximum speed on a large configuration ?
I've recently installed litespeed on our pre production server and when I get all the issues sorted out I will be transfering quite alot of accounts from a smaller server running Apache to this new server.
I've read in various places that setting some options too high will slow things down instead of speeding things up.
Our customers host various scripts (Wordpress, Joomla, PhpBB, vBulletin, IPB and also custom scripts, some better optimised then others).
We're aiming at getting the best performance and stability for our customers websites.
Our server has got 256GB of RAM and 32 * 3.1GHz threads.
I've already activated and configured Xcache 3.0.1 and allowed it 1GB of cache space…
I've run some tests and seem to be getting 503 error messages when there are too many processes being run. By upping LSAPI Max connections and LSAPI_Children from 35 to 400 most of the errors have gone.
I want this server to be able to cope with a large number of simultaneous requests and serve each of them quickly. I want to try and get the configuration right before migrating the accounts to it.
Can you guide me to have the right settings for maximum performance and maximum number of processes ? Shoud I pay to have you configure these settings ? Can you do this with only a few customers on the server ?
I've been monitoring the performance of a small php script with echo "hello world" from different locations and have been getting spikes every now and again.
Most of the time the scripts download in 15 to 17ms and then every now and again the latency goes over 500ms…
This server has only got a few medium traffic sites on it so it should be stable and have regular latency times. I'm worried that if I get 503 errors and latency spikes what it will be like with 700 or 800 accounts on the server.
The server load is always below 1.5 for the mement, this includes MySQL and other services so I don't think I'm being limited by the 2 Core test licence… am I ?
