Build PHP in LSWS
===============
Once LSWS is installed, you need to build matching PHP within LSWS so that PHP in LSWS (LSPHP) has the same function/extension support as the one in Apache. We have the following documents to help you go through that process.

License
======
You can start on a Web Host Professional trial license and upgrade to a Web Host Enterprise or Web Host Elite license at any time.

Some factors to consider:

What other processes are running on the same server?
For example, if you have a 4 core server and run LSWS, PHP, and MySQL on the same server, it might be best for you to buy a Web Host Essential or Web Host Professional license, use the other cores for your PHP and MySQL processes. Usually, on a 4 core server, you will not need higher than a Web Host Professional license, if you have external applications like PHP or RoR. Upgrading from a Web Host Professional to a Web Host Enterprise license will not help much if your bottleneck is PHP, RoR, or MySQL.

Do you deal with high volume HTTPS traffic?
LSWS will require more CPU power for encryption.

Do you mainly serve static content (like images, file downloads, etc.)?
These are served by LSWS directly, so more CPU will help.

What is your disk I/O wait?
Like all other lightweight web servers, blocking disk I/O will block LiteSpeed processes. If your server has a high I/O wait, you should consider a higher CPU license in order to compensate.

Support
