Hi people, im using Debian Sarge with samba 3.0.14a. Im using tdbsam 
with 400 users.
My specs are:

model           : 8
model name      : AMD Athlon(tm) XP 2000+
stepping        : 1
cpu MHz         : 1670.860

bogomips        : 3309.56

             total       used       free     shared    buffers     cached
Mem:        516608     509516       7092          0      96988     337520
-/+ buffers/cache:      75008     441600
Swap:       979956        664     979292


My idea is to start using samba-vscan + clamd to check my fileserver.
Questions:
Anyone using this on a production server? Comments?

How much this would impact on my performance?
