Hi
I have a samba server (3.4.3-2 lenny version). This server is a PDC
with roaming profiles.
was migrated from an old woody server.
Some times, all the users report me low performance when run an app
shared on a public folder. The app is an access database. Some
times work very fast, some times work very slow.
how can i detect the reason of the low performance? the cpu, memory
process and swap usage is always minimal. Never show heavy process.
This is a virtualized server (i use Xen). The virtualization can
affect the samba performance? the virtual server has four times more
resources than the old server.
thanks and regards.
