try increase memory soft/hard limit for CGI. http://www.litespeedtech.com/docs/webserver/config/security/#memSoftLimit

You need to fix the rewrite rule on line 91 in the .htaccess .

You can check the php.ini search path from phpinfo() output and put php.ini there.

The LVE is a interesting feature. We can add some code to support that.

We will follow up with Igor .

It is not possible, and not that important, use the same value for all users should be fine.

How are those vhosts being configured? Are you using a control panel?

Thanks for the fix, we will apply the change to next release.

The default lsphp5 configuration is optimized for shared hosting environment, if you server serve a large web application, no need for PHP suEXEC, then you can increase "Max Idle Time", or set it to "-1". It will reduce number of DNS requests, will speed up a little bit.

If your PHP script need to communicate with remote server, you need to make sure DNS is fast. A local forward DNS server which can cache DNS result is highly recommended. Your server load is not high, no mysql, so I guess most PHP are just waiting for the remote server, blocking on sockets...

Make sure LiteSpeed PHP exactly matches Apache's PHP, check and compare phpinfo() output from both.

Check your server "Log Level", change to "INFO".

If it is cPanel server, you need to link against /opt/libxml2/lib64 .

You can try $fileStat->size = sprintf("%u", $s[7]); it limit to 4GB due to PHP limits on 32bit system.

You need to increase the per process file descriptor limit http://www.litespeedtech.com/how-tos.html#qa_incfd

If you stream media file through PHP, you need to increase the response body size limit under server->tuning tab. Or, better using Internal redirect to serve those media file as static file. http://www.litespeedtech.com/support/wiki/doku.php?id=litespeed:wiki:feature:internal_redirect

It depends on how fast a request can be finished, if request need 5 seconds to finish in average, if the server got 20 new requests per seconds, you will get 100 requests in process and 20 requests/second rate. The solution is to optimize your PHP and MySQL to make it faster and take less time...

It is number of seconds. If PHP suEXEC is used, each account get a few dedicate PHP processes, this should be set to a couple seconds, like 10 or 5 seconds. Other wise, there will be too much PHP processes running and consume too much system resource by idle PHP processes.

We are still working on it. :)

xcache works with LiteSpeed, if you do not use PHP suEXEC, it is just not friendly with PHP suEXEC.
