This is to report whole 6.7RC got slow disk performance, I have setup as below
- 3 disk connect to LSI HBA
- 1 SSD connect to onboard SATA
- each disks have only one 24GB file for testing
- same issue reproduce on 3 different PC platform
Test by cat /mnt/disk(x)/xxxx > /dev/null
In 6.6.7, even 3 disk read at same time, throughput was normal
But after 6.7RC, even onlyone disk access, throughput already drop.
