-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1Hi! I have a user who is running a Samba server to store data files for his ArcView 3.3 application. Client operating system is Windows XP professional. With Samba2 (2.2.8a) this was working quite fine, it usually took less than a few seconds to load and render one of the GIS presentations with ArcView. We then did an upgrade to Samba3 (3.0.20b) and suddenly the same operation now takes more than 20 seconds or even minutes in some cases. You can even see the picture forming slowly on the screen. Other applications do not suffer from performance problems (The new Samba3 server is a really fast Dual Opteron server with 4GB of RAM and a fast external U320 RAID running under Linux-2.4.31) I took a IP traffic dump with tcpdump and also samba logs with loglevel 10 and found that there are a _lot_ of small packets going between the WinXP client and the Samba3 server. [global] socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 kernel oplocks = Yes lock spin count = 3 lock spin time = 10
