PROTON-1520: C proactor epoll performance. Defer writes until after event
batch processed,
defer rearm until after write
> C epoll proactor delayed socket writes
> --------------------------------------
>
> Key: PROTON-1520
> URL: https://issues.apache.org/jira/browse/PROTON-1520
> Project: Qpid Proton
> Issue Type: Improvement
> Components: proton-c
> Affects Versions: proton-c-0.18.0
> Environment: epoll (Linux)
> Reporter: Cliff Jansen
> Assignee: Cliff Jansen
> Fix For: proton-c-0.18.0
>
>
> The epoll proactor currently processes socket output immediately after
> processing socket input, and following that processes events (which can
> generate more output, including protocol handshakes). This has the
> unfortunate effect of requiring an additional system call and thread context
> switch to handle this resulting output.
