[Freedos-devel] More speed test

[Johnson L. <jo...@tm...>]

Hi,

Thanks to Jack Ellis, he did help me to test HIMEM 3.10 and FDXMS
0.94. Even under MS-DOS the memory manager DO affect hard disk
accessing speed ...

I ran 4 tests unzipping my 2.2-GB "zeros" file onto my C: drive (it
uses only 74-MB for files without Win/XT's PAGEFILE.SYS and so has
2.07 GB free).   The test results were:

     A) FDXMS, no XDMA overlap:      54.0 seconds.
     B) FDXMS, XDMA output-overlap:  41.5 seconds
     C) HIMEM, no XDMA overlap:      47.0 seconds.
     D) HIMEM, XDMA output-overlap:  42.5 seconds.

The example is really good to explain memory manager REALLY affect
speed! But for the FreeDOS HMA ... will it really consume so much
time?

Any kernel people previously take care of this?


Rgds,
Johnson.
