- using 5.5.0 - using KahaDB store - publishing to a topic with 10 durables (offline at the time of the publish rate test) - message size 500 byte
cannot get over 2.5MB per second disk write (approx 5K messages per second). tried local disk, ssd, tmpfs ram mount and Windows PC - nothing helps. the rate is stable whether I publish 25K messages or 40 million messages :( KahaDB message store is kept in memory, so I guess it is only the journals that are being written. I doubt this is TCP issue. Have plenty of CPU (16 core box with 128GB of RAM). ActiveMQ disk benchmark tells me I should get 2600MB per second write, which is a bit optimistic but certainly better than 2.5 mb :( help! -- View this message in context: http://activemq.2283324.n4.nabble.com/disk-IO-rate-peak-tp3504958p3504958.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
