Work Description: franz1981 commented on issue #2523: ARTEMIS-1977
ASYNCIO can reduce sys-calls to retrieve I/O events
URL: https://github.com/apache/activemq-artemis/pull/2523#issuecomment-458851476
This PR doesn't change anything specific for being 32/64 bit, but like any
changes on the native layer, having cross-compilation would help (me or anyone)
to provide the 32 bit binaries without pain.
IMHO it should be better to have the cross-compilation PR of Otavio merged
first and I would use it to cross-compile this PR, but I prefer to have them
separate if, for ANY reasons, one of them will need to be reverted, they
weren't tied up together...

> On LibAIO is possible to retrieve the I/O completion events without
> using io_getevents sys-calls by reading the user-space ring buffer used by the
> kernel to store them.
> This is already beneficial for very fast disks and necessary for further
> improvements
> of ASYNCIO Journal to leverage (very) fast low-latency disks by going
> completly
> lock-free.
