I'm pretty tired about this topic because Mr. Eric talk a lot but things still not clear, maybe I'm too stupid. Maybe misunderstanding, I remember Alain said after he use UMB, FreeDOS slowdown a lot and need to use UDMA2 and cache to reclaim the speed. I'm sure UDMA or the latest XDMA is NOT a factor of slowdown, nothing related (in my test or Alain's test), please stop bring two problems together, thank you. Sorry but Jack have no interest in LBAcache because he use Norton Cache, so he just care about the integrity of his own program. He explained before he follow the proper procedure, and agree with Tom's analyze, the reason that caused slowdown maybe the int21h requests accessing the HMA and perform the requests a sector at a time. IMO, maybe reduce the BUFFERS=1,0 and try using cache (LBAcache or others) may improve performance.
