Turning off windows quality of service seems to have given me sustained write speeds hitting about 90MB/s using cifs wites to the ISCSI device are hitting about 40mb/s but the network utilisation graph is very jagged, it's just a constant spike to 60% utilisation then a drop to 0 and repeat I

I'm currently experiencing exactly the same problem and it's been driving me nuts. Tried open soalris and am currently running the latest version of SXCE both with exactly the same results. This issue occurs with both CIFS which shows the speed degrade and ISCSI which just starts off at the

I have just built an opensolaris box (2008.11) as a small fileserver (6x 1TB drives as RAIDZ2, kernel CIFS) for home media use and I am noticing an odd behavior copying files to the box. My knowledge of monitoring/analysis tools under Solaris is very limited, and so far I have just been using

Ok, I'm going to reply to my own question here. After a few hours of thinking, I believe I know what is going on. I am seeing the initial high network throughput as the 4GB of RAM in the server fills up with data. In fact, in this case, I am bound by the speed of the source drive, which tops
