Dear all, I´m running Proxmox 4.2 onto a software RAID of 2 Tb SATA disks of 7200 RPM.
I have set it up using OVH Proxmox installer with ext4. I have realized that another server with just one SATA disk has writes of about 140 MB/s while this server with 2 disks has just writes around 40 MB/s: root@nyserver:~# hdparm -Tt /dev/sda /dev/sda: Timing cached reads: 11800 MB in 2.00 seconds = 5903.84 MB/sec Timing buffered disk reads: 136 MB in 3.17 seconds = 42.94 MB/sec root@myserver:~# hdparm -Tt /dev/md4 /dev/md4: Timing cached reads: 11356 MB in 2.00 seconds = 5682.49 MB/sec Timing buffered disk reads: 132 MB in 3.10 seconds = 42.52 MB/sec I´m running 4.4.15-1-pve kernel. Is there any way to improve the performance of writes? Thanks!
