Hey, bragging time :-) Using one 3.2 smbclient against smbd reading off RAM disk I've seen more than 700MBytes/second over 10GigE where the raw TCP speed was not much more than that. With real client apps reading consecutive small files using the just-added preopen module the performance was more than 300MBytes/second. But here we had to hand-tune the server using the preopen module to completely hide the file system latencies. Executive summary: smbd is no real bottleneck, it's client behaviour and the rest of the infrastructure that limits you. Performance tuning to those numbers is not really easy though, you really have to look at all components on the path from the Win32 app down to the raw rotating disk. Volker
