[Samba] Samba performance issues

[John Coston]

some output from ps wauxf:
for  smbd, all the processes are around this value:
parky     1963  3.5  0.1  7488 3452 ?        R    07:37  15:41  \_ smbd 
-D
for ldap, all of the processes are around this value:
ldap      6150  0.0  0.1 75548 5068 ?        S    14:45   0:00      \_ 
/usr/sbin/slapd -u ldap

we have about 30 of each process running right now. If I understand 
this correctly, it means that I have 30 ldap processes that are each 
using 75 MB of virtual memory, which would be 2.25 GB virtual memory 
for all of them.

here is the output of cat /proc/sys/vm/bdflush - this seems to indicate 
that the vm is flushing every 5 seconds as indicated by vmstat?
  [root at student0 root]# cat /proc/sys/vm/bdflush
40      0       0       0       500     3000    60      0       0

I'll have to wait for downtime this evening to test with ldap down.
