Do each of these LIST operations take a long time to perform? >>> read(0, "00000002 LIST \"\" INBOX.*\r\n", 4096) = 26 >>> read(0, "00000003 LIST \"\" user.*\r\n", 4096) = 25 >>> read(0, "00000004 LIST \"\" *\r\n", 4096) = 20 Maybe I'm losing track of the original thread... You said there was high cpu usage and slowdown during login. Did you track it back to these LIST operations?
