Aplication slow after migration
Hi, everybody!
I have been using samba on Debian for years on my file server and I
have recently migrated from an 4 year-old HP DL server running sarge to
a brand new HP DL server running etch.
Once the new server was configured I noticed some latency on network
shares, but I considered unimportant.
The problem came on one or our applications. It stores its data in a
shared folder distributed over 29000 files about 1k-40k and is so much
slower when it runs on the new server.
I have thoroughly revised both old and new smb.conf files, but can't
see significant differences. I also checked network congestion, but I
there is'nt any. It seems to me like a network latency problem, more
than a Samba-specific issue.
I've made this rudimentary test, and old server is quite faster, but I
don't know if it is meaningful at all or how can I tune it up.
felipe@nils:~$ ping -i 0.2 fast_server --- fast_server ping statistics ---
2156 packets transmitted, 2156 received, 0% packet loss, time 431208ms
rtt min/avg/max/mdev = 0.135/0.171/0.245/0.018 ms
felipe@nils:~$ ping -i 0.2 slow_server
--- slow_server ping statistics ---
2146 packets transmitted, 2146 received, 0% packet loss, time 429165ms
rtt min/avg/max/mdev = 0.152/0.179/0.333/0.021 ms
Old kernel is 2.6.8 and new one is 2.6.18-4-686.
Samba version: 3.0.14a-3sarge2 vs 3.0.24-6etch4
Thanks in advance
