-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
I have the following system set up: Server: Ubuntu 7.04, Samba 3.0.24, http://www.esuna.co.uk/~jay/misc/smb.conf Client: Vista Ultimate 64-bit, NetBIOS over TCP/IP disabled, LMHOSTS lookup disabled. Share mapped to drive Z:. Up until a few days ago this was working fine. Read/write transfer rates of over 20MB/s onto a RAID-1 array, speedy browsing. But yesterday I noticed a drop in browsing latency; there's now a short but noticeable delay before directory listings appear. Cygwin's ls (which I assume was inefficient to begin with, but quite usable) takes 9 seconds to list a small directory. Curiously, *read/write throughput hasn't changed* - it's still >20MB/s. Latency also seems normal if I reboot into an XP Professional installation, or access the share from my Vista Business 32-bit laptop on the same network. The problem briefly seemed to fix itself yesterday after I tweaked the configuration file a bit, but returned to poor performance later in the day; possibly after a reboot but I don't recall. I've upped the log level and can't see any obvious errors in log.smbd or in log.(host). Observing traffic with tcpdump turns up nothing obvious - the exchange goes on for longer but the difference in per-packet latency isn't visible (Samba sure sends a *lot* of packets to list a directory). Any ideas what I could do to trace this problem? Thanks, - -- Jay L. T.
