Hi, I recently built a new server with a i5-3570K CPU, 16GB RAM, an Intel 10G NIC and 45 drives connected using a LSI 2008 SAS card flashed in IT mode.  The drives are split between 30 for the main Array and 15 as a pool using btrfs/RAID6.

 

The performance seems to be somewhat spotty and things seem to really slow down (5-10 MB/s) if I am trying to read from the Array from one client while writing to it from another client.  All networking is via SMB. 

 

Would upgrading my CPU help or is the performance limited given the large number of drives attached?  Are there any performance tweaks that can be performed?

 

PS - There are no vm's running on the box.

 

Thanks!

If this is to/from the array it's normal due to parity, pool(s) should be much faster.
