My move to a VPS account has been a learning experience to say the least, and thankfully I only have a few more issues to get figured out. I Did some searching and I can't find a firm answer for this one, Is the Zend Optimizer pre-installed on VPS hosted accounts (w/Plesk)?

I didn't specifically request it, but I did pay LP to handle my move from the shared server to the VPS so it was probably just missed in the move. I guess my next move would be to open a support ticket and have support set it up for me. It's probably about a 3 minute job for them.

OR... There are two Linux versions of Zend Optimizer available for download, 32bit and 64bit. I can look in Plesk and see that the server is running on Linux v.whatever but I cant find any place that tells me what "bit" version it is.  If I can find out I may tackle the Zend install on my own and possibly learn something in the process.

Hello Aneurysm,

You need to use the 32-bit version. There is no specific location for Zend Optimizer, usually it gets installed under /usr/local/Zend or /opt/Zend. After that, you just need to ensure the Zend library specific for your version of PHP is loaded in /etc/php.ini file where the path to the library is specified.

Please advise, if you get any further questions with regards to this.
