60 millibits per second? 60 bits every 1000 seconds? Are you serious?
Or did we get the capitalisation wrong?
Assuming 60MB/sec (as 60 Mb/sec would still be slower than the 5MB/sec
I
was getting), maybe there's some characteristic that Bluestore is
particularly dependent on regarding the HDDs.
I'll admit right up front the drives I'm using were chosen because they
were all I could get with a 2TB storage capacity for a reasonable
price.
I'm not against moving to Bluestore, however, I think I need to
research
it better to understand why the performance I was getting before was so
poor.
It's a nano-ceph! So millibits :) I mean 60 megabytes per second, of
course. My drives are also crap. I just want to say that you probably
miss some option for your VM, for example "cache=writeback".
The exact commandline I used to start my test VM was:
kvm -m 1024 -drive format=rbd,file=rbd:rpool/debian10-1,cache=writeback
-vnc 0.0.0.0:0 -netdev user,id=mn -device virtio-net,netdev=mn
