Hi, we are currently running ActiveMQ 5.2.0 (using Sun Java 1.5) on
2 x Sun Fire V245 with 2 CPU (Ultra SPARC IIIi 1,5 GHz) and 8 GB ram as "network" of brokers. Everything works fine and is ok. Now I got the question, if our JMS system can cope with the following load: 616 Messages/s (size differs, but will be between a few bytes to 200 kb per message, averaging about 28 kb per message), that makes about 28 MBit/s data. On bursts up to 1900 messages/s will be produces (same sizes as above). I'm now checking for test hardware to check the maximum throughput myself, but since that will take a few days and I need a housenumber what servers I will need to fullfill that request very fast, I though that perhaps someone on the list may help me. For the setup: I thought about setting up a network of brokers with local storage each. How ActiveMQ is affected by switching to Java 1.6? And because I was asked for a housenumber on the spot I told them 20 intel based machines (normally we use HP DL-365 with dual Xeon Quad Core) would be sufficient for the burst load. If I can go down with my estimation, that would be appreciated by our project managers very much :-). bye, Roland -- Roland Thomas Lichti IT Telefónica Deutschland GmbH Hülshorstweg 30, D-33415 Verl Tel +49(0)5246-80-1121 Mobil +49(0)160-98949570 Fax +49(0)5246-80-2121 roland.lic...@telefonica.de Telefónica Deutschland GmbH || Georg-Brauchle-Ring 23-25 || 80992 München || www.telefonica.de Telefon: 05246 80-1080 || Fax: 05246 80-2080 || E-Mail: i...@telefonica.de Ust.-Id.-Nr.
