Hi,
I'm getting poor read performance on some of my shares using CIFS, and I can't see what's going wrong. Read speed is around 10Mbits per second. My network is all gigabit and even 10Gbit to the storage servers. The hardware is an x4540 configured with RAIDz2 and ZIL on a pair of SSDs NFS to the same shares performs about twice the speed. I did a zpool iostat while both the nfs and CIFS read are happening. # zpool iostat dataPool 1 200 capacity operations bandwidth pool alloc free read write read write ---------- ----- ----- ----- ----- ----- ----- dataPool 18.3T 21.7T 578 59 35.2M 1.37M dataPool 18.3T 21.7T 46 0 4.99M 0 dataPool 18.3T 21.7T 231 0 26.1M 0 dataPool 18.3T 21.7T 280 0 31.7M 0 dataPool 18.3T 21.7T 352 0 40.6M 0 dataPool 18.3T 21.7T 348 0 41.1M 0 dataPool 18.3T 21.7T 371 0 45.3M 0 dataPool 18.3T 21.7T 475 0 57.6M 0 dataPool 18.3T 21.7T 409 0 49.7M 0 dataPool 18.3T 21.7T 483 0 58.8M 0 dataPool 18.3T 21.7T 188 0 15.4M 0 dataPool 18.3T 21.7T 143 1.49K 13.4M 5.68M Do you think my machine is at the limit of it's performance?
