Hi Eric,
I don't think any of this applies in my case. I'm running FreeDOS on
real ancient hardware, i.e. 8086 with 640K RAM.
For my purposes, to play some ancient games with the grandkids on my old
machines, the performance is exactly right.

Hi!
I put calls to FREESP, (https://github.com/ChartreuseK/FREESP) in my
AUTOEXEC, (FDAUTO.BAT) and that worked well for me.

Which settings for cache and read-ahead do you use?
I think there is potential to fine-tune things :-)
Also, how much RAM do you have and how many clusters
and files are there on your C: and D: drives?
If the drives are not too big, you could try this
as part of your autoexec bat at boot:
lbacache 32000 flop
tickle /chs /lba
lbacache cool
dir c:\ /s /b > nul
dir d:\ /s /b > nul
lbacache temp
That is supposed to pre-load your FAT and directory
metadata into cache, with read-ahead, and flag it as
"prefer to keep it cached". Cache size e.g. 32 MB.
Alternatively, just load UHDD /S31 for a 31 MB cache
instead of LBACACHE. Your UIDE can be up to 4 GB and
it already has read-ahead built in (UIDE may not?).
You can also use UDVD2 or CDRCACHE to cache CD/DVD,
or UIDE which caches both fixed disks and CD/DVD.
Looking forward to hear about your experiments, thanks!
Eric
