different sizes for same php-page returned?

[ts77]

hey there,

I'm just trying out litespeed 2.0RC3.
I'm using it with php via fast-cgi and turck-mmcache and my app is a forum-software.

I enabled compression ... maybe thats the problem?

Here is the situation:
While running with ab (for benchmarking) I see failed requests reported (failed by size), i.e. around 30 requests of 1000. Yeah, I disabled hardlimit/softlimit and the pages don't change ;-).
If I look at the access-logs the different size is logged there too, i.e. 3002 instead of 2976 bytes or similar small differences.
That makes me curious about the accuracy of the compression.

Any ideas?

BTW. another question: would I see any performance increase in this configuration with the Professional-version as the most load is on the fast-cgi/php-side?


TIA,

thomas
