I have a TX100 and a TX140.
Both mounted with 4*SSD RAID 1+0.
TX100 = superb disk performance. 600 MB/s read, 500 MB/s write.
TX140 = ugly disk performance. 800 MB/s read, 3 MB/s write.
only 3 MB/s on write operations !!!
3 MB/s is painfully slow, that I can tell you.
What is happening folks ?
This is a production server and users are annoyed. Sad !
I suspect the write cache setting, how do you mess with this ?
