...... In general, there's no magic bullet for performance. It depends on your hardware, your operating system, and how your users use the system. In general, an imapd process takes up anywhere from 256 Kbytes to 512 Kbytes of memory When it is first fired up. ....... But when I use the pmap command I see that the memory est private spending more than 512Kbytes. pmap -d 32407 32407: imapd Address Kbytes Mode Offset Device Mapping 0000000000400000 1452 r-x--
