franz1981 edited a comment on issue #2844: ARTEMIS-1811 NIO Seq File should use RandomAccessFile with heap buffers URL: https://github.com/apache/activemq-artemis/pull/2844#issuecomment-533906809 I'm going to "tune" the optimization while reading/writing RandonAccessFile in chunks of 8192, because on https://github.com/netty/netty/pull/9591#issuecomment-533904873 I've measured that the allocator isn't a bottleneck when chunk size > 8192 and assuming single threaded usage (malloc -> free on the same thread). ATM AMQP and OpenWire could cause big buffers allocation on native space (on JNI), so I would reduce the impact of this by tuning chunk size just to reduce the foot print overhead of it.
