On Thu, 14 May 1998 Jonathan Roberts posted his configuration files.
Here are a few suggestions to improve performance, and get a better
memory footprint:

AUTOEXEC.BAT:

> C:\MSCMOUSE\gmouse.com
LH C:\mscmouse\gmouse.com

> SET TEMP=C:\DRDOS
Tz, please avoid using such directories as trash/junk directory... ;-)

 MD C:\TMP
 SET TEMP=C:\TMP
 SET TMP=%TEMP%

> NWCACHE 7670 1024 /LEND=ON /DELAY=OFF
VERIFY OFF
LH NWCACHE 7670 1024 /LEND=ON /DELAY=5000

> LH /L:2,55168 COMMAND /E:1024 /CC:\utils\fos.bat
???

> ****** CONFIG.SYS *
As already said in the replies, please try to defragment your UMB area 
to get a single continous chunk. This will reduce left-over unused 
areas, and also will allow to loadhigh much larger drivers.

> DEVICE=C:\DRDOS\EMM386.EXE DPMI=OFF FRAME=AUTO
I would also suggest /VIDEO=ON and /XMSUMB. For advanced purposes, 
I would also use /USE and /RAM options. Since you're using NWCACHE, 
you should load DEVICE=c:\drdos\dmps.exe here, too.

> BUFFERS=15
If you were not using a cache, I would increase this to 30-40,
using HIBUFFERS=35. However, I would prefer reducing this to
3-10 and loading NWCACHE instead. This will give you much better
performance.
HIBUFFERS=5
> FILES=30
FILESHIGH=30
> FCBS=16,16
Usually not necessary any more. Try
FCBSHIGH=4,0
> STACKS=9,256
Usually not necessary on compatible machines. Try
STACKS=0,0
> SHELL=C:\COMMAND.COM C:\ /E:1024 /P
SHELLHIGH= SIZE=1B00 c:\drdos\command.com c:\drdos\ /E:1024 /MH /P
I always forget the optimal value for SIZE. Please use the smallest
value, which still allows to load COMMAND.COM into the HMA.
