Samba 2.2.8a and 3.0.0
...AIX 5.2 to determine if
performance can be improved by rearranging the executable generated by the
IBM 6.0 compiler.
Mostly I'm determining what the upper bound on smbd's is in a
multiprogramming environment. I'm currently running about between 800 and
1000 smbd's a day on a 6-way 6H1 (RS64-III) with 24GB memory and 800 GB of
attached SSA disk for roaming profiles. All of this is being done with
2.2.8a.
I'm setting up my 3.0.0 test area on similar hardware, but wanted insight
from the experts on what you've done already to improve internal
performance as my approach is...

Samba and Seq. Read ahead.
...ngs that may be bumped out of
memory before we ask for it since there are 550 WS's asking for roaming
profiles at login time.
Turns out my reads although sequential on the part of the smbd were really
random in the sense that there was an onslaught of calls to the disks
at one time.
System is 6H1 with 6-RS64-III at 668MHz with 6GB memory. Disks are SSA
36.4 10k in 2 6+P/HS raid-5.
Now it seems that single tuning has allowed Samba to work even better than
it has!
Also the addition of O_DIRECT and/or O_NOCACHE to the fd_open() call in
source/smbd/open.c had no significant increase in perfor...

2.2.7a slowness on AIX 5.1-ML03
I have an open PMR with IBM regarding a slowness issue when more than 450
smbds are trying to login and download roaming profiles.
The system is a 6H1 with 6 RS64-III 668MHz cpus and 6 GB memory w/Gb
ethernet. We have over 10,000 student accounts with roaming profiles and
800 XP-SP1 workstations for them to choose from.
I've compiled 2.2.7a in 64 bit and 32 bit modes. Run it on both the 32 bit
and 64 bit kernels. IBM has determined that the...
