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. :confused:

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:

19525 nobody 16 0 42 2:09.60 0.4 13412 11m 1744 S lsphp4
20417 nobody 16 0 27 1:06.83 0.4 13188 10m 1596 S lsphp4
20233 nobody 17 0 12 1:39.54 0.4 14680 12m 1596 R lsphp4

:eek:

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.

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. ;)

You should copy the php.ini used by Apache mod_php then add the eaccelerator configuration.

From command line do "./lsphp4 -v" to make sure there is no error message complaining failed to load eaccelerator.so
You can try removing "extension_dir" configuration in php.ini.

I copied the php.ini from /usr/local/Zend/etc/ to /usr/local/lsws/lsphp4/lib/
removed the Zend lines and added eaccelerator lines.

finally working

*whewwwww*

extension_dir = "/usr/local/lsws/lsphp4/lib/php/extensions/no-debug-non-zts-20020429"
extension="eaccelerator.so"
eaccelerator.shm_size="48"
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"

I got an example from another site and changed it.

Thanks for helping! :)

Yes, I made that folder and set the permissions correctly, there are many folders and files created. Could it be the fact that I put too many configure parameters during the PHP build?

Also, I see this on the process list:

1804 nobody 16 0 0 0:00.04 0.2 7672 5324 1504 S admin_php -c ../conf/php.ini

why is it showing that path to php.ini file?

I'm curious, are you really worried about a high overall load or just because you see php separately now? with apache you probably had mod_php loaded into apache and therefore only saw apache processes with high load. with litespeed php is run separately and gets requests through lshttpd.
If you got lots of php pages / scripts requested than surely php is running high ;).
