elliptics@eblob: 5000 rps of random IO requests in 1 Tb of data (100 millions of objects)
Hardware: 2 E5530 servers (16 cores, 24 Gb of RAM) each one is connected to SAS shelf (14 disks, ext4, raid10).
Data: 100 millions of objects (total of 1042 Gb) roughly equally spread over above server nodes.
Requests: random IO reads.
Result? We have it:
Reply time (left, in ms) @ number of requests per second (right, red inclined line)
Reply time (in ms) distribution
Net result: 3500 rps within 100 ms, 4000 rps witin 200 ms.
Not that bad I think…
