Hi,
I did some bandwidth tests with "rados put/get" (1), (2).
I'm wondering, why "rados get" (read) bandwidth-results are not that good.
If I run
- 1 instance of rados get (2), the bandwidth is about 170MB/sec, with
- 4 instances (2) in parallel, I get 4 times ~170MB/sec == ~ 680MB/sec
Is there a change to improve the bandwidth of one running instance?
regards
Danny
