Hi, I made simple write speed test.
I have 3 nodes:
node1 node2 have 1000Mbps network card.
node3 has a fast ethernet (100Mbps).
On my vm I run
dd if=/dev/zero of=deleteme bs=1M count=512
speed avarage is 7,1MB/s.
I removed node3 from the cluster, because I think it slows down everything.
I waited till the cluster finished to copy the missing chinks, then I
run the same test.
The speed was 9,1MB/s, so still like a fast ethernet.
I was also looking atop during the test on node1 and node2: the disk
was never busy more than 70%.
What do you think about it?
Shouldn't it be faster?
