Hi Daniel, Is that 500Mb/sec with CIFS, copying a directory structure with lots of small files? I can also get 500Mb/sec just doing a local block read.
My problem is that CIFS is very slow, and it seems to get worse as there are more people using the system. We only have about 50 possible users anyway. This morning before anyone was using the system I got 6 Mbytes/sec. - Still not brilliant, as I was probably the only CIFS user. During the day, it's gets down to 2Mbytes/sec Running snoop while I'm reading via CIFS, shows a lot of NBT and SMB traffic going back and forth between client and server, but not much in the way of file transfer. Anyone any clues?
