raoul,

i am fascinated.

did you set any debug log levels?  remember: if you set log level to 100
on TNG, expect a performance hit of about a factor of ten or 20!

did you compile TNG with dynamic libraries or static?  (it's a ./configure
option, the default is dynamic.  it affects the binary size - vastly
smaller: smbd is... urr... 417k in TNG latest cvs instead of.... urr...
2meg?  - but has an overhead of 15% roughly on the actual function calls
etc. and also on the libaries all being PIC - position independent code)

another recommended test:

how long does a domain logon take?

important things to do:

reboot the client in between tests.  wait for the dialog box to come up.
wait for the client disk to stop spinning.  wait another 20 seconds.
_then_ log in, starting the timer from then.

include downloading your user-profile, if you have one.  do not modify the
desktop as you log out.

run this twice (each machine) to make sure.

many thanks raoul,

luke

Subject: Speed comp. TNG & 2.2.alpha


Just in case anyone was interested, I compared the speed of TNG and
2.2.alpha...
This was the setup:
FreeBSD Release 4.1
TNG 2.6 good  vs. 2.2.alpha from CVS
Pentium III 750 with 128MB and 2 Ultra-2LD SCSI Harddisks (18 GB each)
Three shares are set browseable.
Domain logons are enabled. (Win2K and WinNT)

Initial browsing in Windows Explorer (finding drives R:, S:, V:):
TNG: 0.4 - 0.5 s (is slightly difficult to measure, dunno how much is
Windows, how much is TNG related)
2.2.alpha: around 2 s

Copying of 100 MB (mixture of small and big files) from the server:
This was unfortunately mainly limited by the fact that I am sitting on a
10 MBit half duplex network, partially switched.
TNG: 6 minutes
2.2.alpha: 9 minutes
