Seems I am not only one encountering this problem. The reading performance of SMB can not reach 10Gbps which suppose be limited by 10G network and won't lower than 10Gbps. I have tried to set "aio read size = 0" and a few tunable parameters (please refer the below), somehow it didn't work at all, the reading speed still be around 6xx-7xxMB/s, but the writing speed is normally 9xxMB/s. The most frustrated is it is not allowed to rollback to FreeNAS. I think the worst case will be migrating all data into an other server and rebuild a FreeNAS server. Please kindly suggest me if there is any solution. Thank you.
