See this image: http://cl.ly/3V1q283Y41151r0L2A3Y The httpd -n 72 process is under the litespeed thread. As I said, we see these from time to time when a server is really under load, but in this case the load on a 8 core machine is ~2 and these are spawning 2 or 3 at a time.

Sorry, guess my next reply did not save, it is owned by litespeed ├─litespeed─┬─httpd │ └─litespeed─┬─admin_php │ ├─httpd

At times when we see a server under load and struggling we see processes spawned by root with the command httpd -n 41 or some other number. What are these processes? We recently provisioned a new lsws 4.1.7 node and with 6 cores and load of 2 we are seem many httpd -n ## procs. (as if it...

We run many web nodes behind a load balancer. I am curious what if any benefit can be realized with the multi-cpu licence. Someone told be the extra threads just hand static content and even with multi-cpu license dynamic requests are still tied to a single or few parent processess. Please...

Disk iowait is the problem. Wait time shoots up as it is trying to read/write from the SAN.. not fast enough.

This is no good on a large server with hundreds of vhosts. /dev/shm/ea fills up in about a minute. Interrupts, Fork Rate, Load, and Disk I/O all go up and the node becomes unstable. 8cores and 11gb of ram on this machine. Any other ideas on how to run a opcode with suExec affectively?

Simple cron to rm -rf /dev/shm/ea/* every couple hours?

So this is the best scenario then? Enable 1M eAccell system wide, which will essentially force a write to disk as 1M fills up fast. And periodically clean out the disk cache. how often? We have over 800 domains on this box.

So are you saying over time that the disk cache will accumulate and grow for each vhost?

is 1M kinda meh? WordPress will if allowed fill 20-32mb of opcode cache on a single page load. Is 1M for each 800 domains (800mb total ram used for cache) better than nothing i guess?

Hey there, Looking for suggestions on how best to configure the moving parts to take the most advantage of litespeed and an opcode cache. We need to maintain security but want to maximize performance and reduce cpu load. Background: - Litespeed Web Server Enterprise v4.0.17 -- LSAPI in suExec...
