I've been looking at cluster filesystems over iSCSI and AoE, and
on moderate hardware, performance appears to be execrable.
Anyone around have experience with this sort of thing?
For a simple example, I have:
- a network that I can measure 93 MB/s across
- a disk that I can measure 74 MB/s reading
- a best-case ext3 over AoE of 41 MB/s
- a usual-case ocfs2 over iSCSI of 15MB/s
Anyone have a clue about the disparities between disk speed and
transferring data from that disk over the network?
