Hello, dear All: I just made a test for cyrus-imapd-2.1.12 on a single Sun Blade 2000, with 10,000 mailboxes created. I started 10 connections, appending a 16K message to the 10,000 mailboxes simultaneously. While I found there seems to be a limitation of about 1.5 msg/sec on each connection, or a total throughput about 240KB/s (16K*1.5*10).
However, I want to improve the throughput to some degree, say 2MB/s, to support a high-throughput application. So I want to know where is the potential bottleneck of cyrus-imapd, the single pattern? or the backend Berkeley? Should I use the "Murder" way? or should I replace the backend with Oracle? or both of them? Thanks for any help! BR, Lin Feb 13, 2003 [EMAIL PROTECTED]
