Mysql benchmark with/without libaio: http://www.bullopensource.org/posix/Bench/sysbench-oltp/results/test1/test1.html Lighttpd benchmark using aio - http://blog.lighttpd.net/articles/2006/11/12/lighty-1-5-0-and-linux-aio Prevayler will be notified when write finishes but it will not block while this operation is processed. It can process Queries while kernel is writing on disk. It's possible to achive something similar with a separete java thread, but it'll require a thread-safe Queue (with sync/locking code involved) and probably will not outperform kernel aio. But maybe is too soon to discuss that :) 2011/9/14 Klaus Wuestefeld <[email protected]> > > Klaus.. this async I/O stuff can lead to great preformance improvements.. > > Any benchmarks we can see? > > > We > > can ask the journal to serielize objects and a callback will be called > when > > it's finished.. maybe not a default behaviour but as an option i think > that > > would be great.. > > Prevayler needs to know when writes are finished.
