Attention Power Users: 
 
Welp, I have delved into looking into the latest config analysis 
and will summarize my FINAL tweaking to my 20 meg OS/2 system 
with enhanced IDE controller and 540 meg drive. 
 
1) IFS=C:\OS2\HPFS.IFS /CACHE:2048 /CRECL:64 /AUTOCHECK:CD 
   If you don't have HPFS, remove any reference to HPFS
2) Removed IBM2FLPY.ADD 
3) SET RESTARTOBJECT=STARTUPFOLDERSONLY 
4) SET KEYS=OFF (This saved me a little mem) 
5) PRIORITY_DISK_IO=YES  (Personal Preference--when bbs is up--NO) 
6) FILES=30 (For DOS sessions) 
7) BUFFERS=90 (Good for floppy access, less mem dictates lower buffers) 
8) MAXWAIT=2  (Things are a little more responsive.  Set to 1 if BBS) 
9) RUN=C:\OS2\CACHE.EXE /MAXAGE:7500 /DISKIDLE:60000 /BUFFERIDLE:60000 
10) SWAPPATH=C:\OS2\SYSTEM 2048 8192  (I saw it go to 8 ONCE-so I chose 
                                       to set it there.  Personal pref. 
                                       'OS/2 Unleashed' says to place the
                                       swapper.dat on the most used 
                                       partition of the least used drive)
11) THREADS=512  (Since I have the memory to waste. I doubt I would need 
                  more than 100.  I chose 512 for that rare moment) 
12) PRINTMONBUFSIZE=2048,134,134  (awesome!) 
13) FCBS=4,2  (FCBS is an old cow so I put the mins in to save some mem) 
14) I REM'd out all references to TCPIP as I don't have a local 
provider. 
15) I REM'd out the refrence to DISKCACHE as I don't run FAT.  SAVED 
    2 MEG due to the "D" switch enabled!!! 
 
As you can see, I scrunched memory where I could and placed it in areas 
that starve for it, ie CACHE, BUFFERS, PRINTMONBUFFERSIZE etc... 
 
System Information says I have 4.5 meg allocated to OS/2 and the rest is 
FREE. 
 
This advice should be ok for 16 meg machines too.  On 12 meg machines, I 
would bring down the THREADS, PRINTMONBUFSIZE, and CACHE a notch.  On 8 
meg machines I would go no more than 1024 cache.   
 
If this helps anyone out, let me know! 
 
Also, if anyone wants to add some advice, feel free to email me the 
info.  Updates are provided as new info is received.
 
Respectfully,
