I was running some sysbench OLTP tests on a dual E5-2699 V3 server. I saw some extremely strange results. These drives were coping images via DD about 3x as fast as the S3700 + SanDisk LB406s (400GB SLC) drives ZFS mirrors in the Las Vegas colo.
Setup:
Seems like there is something going on with the NVMe drives.
Setup:
- Proxmox VE 4.0 (Debian Jessie)
- SSDs set as ZoL mirrored SSD pairs
- Stock drivers
- Dual Intel Xeon E5-2699 V3 server
- LXC containers with Ubuntu 14.04 using the ZFS mirrored pairs of drives as storage 8 cores dedicated
- Sysbench OLTP tests against MySQL 5.6
- Containers were run using the exact same test setups
- 2x Intel DC S3710 200GB
- 2x Intel DC P3600 400GB
- 2x Samsung XS1715 800GB
