[sheepdog-users] 答复: 答复: sheepdog R/W speed from remote Server is very bad than loacal access

[redtone]

Do you means I will get better performance with 3+ servers running sheepdog
in storage mode? 
How to get better with sheepdog?

Copy 1 on a single server, you are gaining none of the
functional/performance benefits of sheepdog with that but picking up
overhead.  It's a corner case as far as a system like sheepdog is meant to
address, performance is very likely broken in that case.  You would do
better to run nfs, or some other solution.

When I run VM on server A. the virtual disk read speed is 450M and the write
speed is 150M When I run VM on server B. the virtual disk read speed is 30M

Is copy = 3 ?
In such case write speed it right to be ~ 30MB/s because it's 1Gbit/3.
Read speed should be higher, near 1Gbit/s so 100-120M/s.
How do you test read and write speed?
