Best configuration for PHP LiteSpeed SAPI

[jeff]

Hello All!

I have installed LiteSpeed Web Server 2.1.1 Standard Edition on linux (Trustix 3 / kernel 2.6).
For test I have compiled PHP 5.0.4 in FastCGI and LiteSpeed PHP SAPI mode.
In my all benchmarks tests with ApacheBench the php in FastCGI mode is more fast than PHP SAPI :

ab -c 298 -n 10000 "http://myserver/phpinfo.php" (LiteSpeed PHP SAPI):
Concurrency Level: 298
Time taken for tests: 33.717688 seconds

ab -c 298 -n 10000 "http://myserver/phpinfo.php" (LiteSpeed PHP FCGI):
Concurrency Level: 298
Time taken for tests: 19.784013 seconds

I have tried many options in theLiteSpeed server configuration for LiteSpeed PHP SAPI, but LiteSpeed PHP FCGI always win.

What the best LiteSpeed Standard Edition PHP SAPI server configuration for the following parameters?
Max Connections?
Environment?
Response Bufferring?
Auto Start?
Instances?
Priority?

Thanks,
