I like the software, but...
The upgrade fee for the 8-CPU owned license is crazy. This is in no way against the developers or their product. The price for upgrades should not be tiered and should fall to a flat rate, in my opinion. This is especially true when you consider that the code is likely forked to create CPU-restricted copies. Litespeed could be the most used web server on the Internet if they eased up on the pricing.
