Many thanks for your continued dedication and improvements. Yes, it does seem that 16-KB cache blocks provide more efficient transfers when many small files are involved, such as exist in your \windows\system32\ files directory. Am I correct that the logic works the same as a cluster-size on large hard disks, ie there is always some "slack" space involved with every file transfered? So, it would seem that 64-kb block sizes will be most efficient in terms of speed, for large files and 16-kb best for smaller files?

I am the guy with lots of memory (8 GB RAM) and can confirm that the 4 GB cache option works well and properly. As I am only able to access 3584 MB total RAM in DOS due to framebuffer limits, I did test on files of 2047 MB and 1024 MB (3 GB total) and all was cached at blazing speeds (at least 1.2 GB/sec) to the best of my timing ability.

I would like to test QCACHE on a *single* file > 2 GB, but this requires a 64-kb cluster size FAT16 partition, which I will set up and try... I'll start with a 3072 MB file and work from there.
