Performance Tuning

[zoom]

I'm trying to determine what would be a good configuration for a site getting on avg 12000 hits per day. I'm running on a VPS with 2GB memory with the LiteSpeed Enterprise version. Are the settings below acceptable?

Max Connections: 500
PHP_LSAPI_MAX_REQUESTS=500
PHP_LSAPI_CHILDREN=50

Memory Soft Limit: 500M
Memory Hard Limit: 550M
Process Soft Limit: 500
Process Hard Limit: 550

DDOS Settings:

Per Client Static Reqs/sec: 200
Per Client Dyn Reqs/sec: 200

[mistwang]

change "Max connections" to "50", it must not be higher than "PHP_LSAPI_CHILDREN"

Your DDoS setting does not protect you from request flood at all, start from

Per Client Static Reqs/sec: 20
Per Client Dyn Reqs/sec: 1 or 2

What is the soft and hard limits under the Security tab?

anewday,

The Server Level settings for "External Application Resource" are as follows.

CPU Soft Limit (sec): 300
CPU Hard Limit (sec): 600
Memory Soft Limit (bytes): 250M
Memory Hard Limit (bytes): 300M
Process Soft Limit: 400
Process Hard Limit: 450

I'm not sure if these values come into play since I'm setting the External Application resources at the vhost level.

[anewday]

CPU Soft Limit (sec): 300
CPU Hard Limit (sec): 600

There is no global setting for these.

Yes there is a global setting at the Server level for the CPU Limits. However, the global settings (below) seem to be acceptable.

CPU Soft Limit (sec): 300
CPU Hard Limit (sec): 600

Using a soft limit of 300 seconds of CPU time for an external application should be okay in my situation.

[anewday]

I don't see the global settings for those under External Apps for lsphp4 or lsphp5.

What are your soft and hard limits for connections under the DDOS settings?

I recommend putting 20 for connection soft limit and 30 for connection hard limit, and set the grace period to 15 seconds and banned period to 2500 seconds.

You'll have many banned ips with those settings.

I've never had a problem with those settings. Pretty sure they're the same settings mistwang recommended in one of his posts a while back.
