Hi,
As discussed on another thread, I've hacked the remote get to only go to a
single node. The performance of put almost doubled, whilst the one of gets
decreased by about 10 percent.
The performance decrease for gets is understandable, but I can't really
understand why the write got so very fast. The OOB thread pool is not shared
between the writes and the reads...
Are both reads and writes marked as OOB ? Then they share the same OOB
thread pool !
That makes me think that there might be a contention point between
OOB and regular threads?
Both regular and OOB message are added to the *same* receive window on
the receiver side, so there are definitely contention points between them...
