Optimization question

Hi,

my vps have 3 gb of ram and only 1 gb is utilized, any way to allocate more memory to litespeed with more child / worker threads or perhaps caching, I hope memory cache is much faster than disk/page cache so in case of memory cache disk i/o restriction would be lifted and memory i/o would be utilized.

any thought/suggestions for tuning vps/litespeed to entertain maximum requests without giving any timeout error etc???

LSWS caching (page cache) is only available for 2-CPU Enterprise license or above and not for 1 cpu license.

you can use opcode cache to speedup php (compile) and application cache option like Super Cache for WP, etc with shm.

what kind of timeout did you get? any error message in error log?

No error message in error log, but it appears in client site.

How can I use LSWS to use memory for caching in order to avoid or reduce disk i/o ?

How can I see historical graphs of my litespeed concurrent connection in past to know what's the max concurrent connections that I may have ever reached ?

Awaiting detailed insight / answer.

Thanks

to use memory for caching, as pointed out previously, you can use opcode cache (i.e., APC, xCache, etc for compiled php code) AND application cache like WP super cache, etc with shared memory (/dev/shm) as storage.

for history data, use tools like cacti, rrdtool, awstats
