In some of the recent performance tests on gluster-as-vm-image-store
|
|
|
887953 |
use-case, it has been observed that sometimes the lone fuse thread can
|
|
|
887953 |
hit near-100% CPU utilization and become a performance bottleneck.
|
|
|
887953 |
Enabling client-io-threads (in addition to bumping up epoll threads on
|
|
|
887953 |
server and client side) has shown to be helpful in getting around this
|
|
|
887953 |
bottleneck and pushing more IOPs.
