I don't know why it's using a lot of CPU and are there 2 instances running because the server is on a Dual Core Xeon 3060? Since installing Litespeed, the load has been higher than when Apache was used.

Have you installed a PHP opcode cache?
LiteSpeed's gzip compression may contribute to the higher load, your Apache installation may not have it, so turn it off under server->tuning tab if it concerns you.

I'm not using any opcode cache. Gzip is already disabled.
I'll recompile PHP 5.
this just happened:

Which PHP version is used with Apache? PHP4 or PHP5, you should compile and use the same version of lsphp.
Install a opcode cache like eAccelerator will help a lot.

Apache is using PHP4. I thought you said it doesn't matter the version that cPanel/Apache uses since Litespeed is installing to a different location.
I just compiled LSAPI PHP5 via the GUI, according to phpinfo, it says the php.ini file is in /usr/local/lsws/lsphp5/lib
but I do not see the file there. Need to add the eaccelerator lines.

Yeah, it is fine.
But, if you want to compare performance, you need to use similar setup for both. PHP5 is slower than PHP4.

You need to create the php.ini file for PHP5 and added the eaccelerator line manually.

I copied php.ini file from /usr/local/lsws/php/php.ini to /usr/local/lsws/lsphp4/lib/ then added the following to the end of the file:
Code:
extension="/usr/local/lsws/lsphp4/lib/php/extensions/no-debug-non-zts-20020429/eaccelerator.so"
eaccelerator.shm_size="64"
eaccelerator.cache_dir="/tmp/lswseaccelerator"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
BTW, I decided to use PHP4 for now. Restarted LiteSpeed, it still doesn't show eaccelerator being used.

this shows up in stderr.log
PHP Warning: Unknown(): Unable to load dynamic library './/usr/local/lsws/lsphp4/lib/php/extensions/no-debug-non-zts-20020429/eaccelerator.so' - .//usr/local/lsws/lsphp4/lib/php/extensions/no-debug-non-zts-20020429/eaccelerator.so: cannot open shared object file: No such file or directory in Unknown on line 0
Any help would be appreciated, if I can get this resolved..I'll seriously considering buying the license.
