Hello.
It seems that corosync gives a very long latency on a one-node
configuration.
We have developed a small test passing messages between two threads.
Each message carried an original tsc timestamp counter value, so we have
been able to compute the difference with the receiver's tsc.
1 (100-bytes) message pass took about 200 us.
30000 messages batch gave about 2 ms.
Some ipc ring-buffer implementation using eventfd showed us less than a
1 microsecond between two processor cores to pass a 128 byte message in
a 1000 messages batch.
So, what's the source of such relatively high latency?
Thank you.
