When L1/L2/L3/L4 are set to 0, xy-VSFilter has a major slowdown and twice twice 
the CPU utilization as VSFilter 2.39. Normally you shouldn't be disabling the 
caches, I don't believe this should be happening.

VSFilter 2.39 has a creepy cache mechanism indeed. In current xy-vsfilter, the 
original cache has been totally replaced with the new cache system, in which 
cache L1 and cache L3 take over the work of the origin cache and do more. So if 
disabling all caches, especially L1/L2, surely it would be even worse then 
VSFilter 2.39. My fault that I forgot to add a warning to warn people not to 
disable all caches.
