performance problems with applications

I'm using SAMBA 2.0.0 an a Linux Box 2.0.36 P133/128MB 100MBit Ethernet
in an NT Domain with an NT PDC and NT Workstation Clients (SP4) 10 MBit
Ethernet. I run samba in the "domain" mode.
Coping files is very fast (a lot of small ones or big ones), but if a
want to start an Application (written with PowerBuilder 6.0) it takes a
long time (18 sec). The Application EXE file is about 2 MB big, the DLLs
are about 5 MB.
Starting this Application from a NT Server takes about 4 sec. This is a
*very* big difference. I'm working an this problem for two weeks now,
trying every hint from Speed.txt.
The funny thing is, if a start it from a samba-Linux box with P90 and 10
MBit ISA Etherent, its a little bit faster (12 sec). So it doesn't
depend on the hardware.
With the Performance monitor of NT you see very good, that accessing a
NT Server there is one big peek with the maximum bandwith - accessing
samba there are some small hills over a long period.

Please help me, otherwise I have to use NT and that would be very bad.

Thanks Armin
