Does TurboIIS recompress every page upon request?
Only if you want it to do. Otherwise, one of the pluses of TurboIIS is its Used Resource Dynamic Control: TurboIIS defines the compression policy, by deciding what to compress and when to update. It has a built-in cache directory, so that it compresses contents only when they change or they are dynamic. This way it eliminates CPU and memory overload, thanks to the intelligent control of the compression level.
