you've indeed been very patient  ;-))

I fully agree, I really looked for the parameters to set, but I don't
think there are any, there must be a lot of debugging code left in the
executable, cause Robert has sure done a good job on his new baby.
here we go, my test results:
I'm using a 80486/33 machine with 16 MB RAM and
the directory I did the tests on had
       68 file(s)   18.221.562 Byte  in it
.EXE
       17 file(s)    3.074.916 Byte
.COM
        2 file(s)       12.551 Byte
.OV*
        1 file(s)       50.544 Byte
.DLL
       19 file(s)    3.124.847 Byte
.HL*
       10 file(s)    9.931.886 Byte
If anyone likes to do it all over again on his/her own computer, it's the
Borland Delphi ..\BIN directory I used for testing
1. PKZip with option  -eX
P-TEST   ZIP  10.420.626 29.10.96   22.50
sorry, no time information, got lost somewhere
------------------------------------ 
2. ARJ with option  -m1 (default)
6 minutes; 30 seconds
P-TEST   ARJ  10.493.528 29.10.96   22.57
------------------------------------ 
3. RAR with option  Solid-Archive
10 minutes; 3 seconds
P-TEST   RAR  10.095.946 29.10.96   23.07
------------------------------------ 
4. UC2 with option  Tight compression
7 minutes; 35 seconds
P-TEST   UC2  10.343.742 29.10.96   23.14
------------------------------------ 
5. Limit with option  -mx
7 minutes; 53 seconds
P-TEST   LIM  10.381.666 29.10.96   23.22
------------------------------------ 
6. JAR with option  -m4
19 minutes; 18 seconds
P-TEST   J    10.277.674 29.10.96   23.42
So, come on Robert, there's a lot of things to be done ;-)
Have a nice day, Lars!
