[Dovecot] Does Dovecot 2 need more ressources than 1 ?
Hello
Switching for Dovecot 1 to 2, I noticed the machine respond slower to users requests , of course it works but response times are a bit longer.
Does Dovecot 2 need more system ressources ? ( the machine is the same )
Thanks

Please provide data that demonstrates the difference in response times. Also please tell us what other changes you made when switching from 1.x to 2.x, such as conversion from mbox to maildir or dbox, implementing LDA, LMTP, sieve, etc.
2.x should be no slower on the same hardware compared to 1.x

I did not change format ( MBOX ) I use IMAP IMAPS POP3 POP3S
Before I switched I removed all .imap cache directories
The machine is a proliant DL380G7 with 12 Gb RAM with FreeBSD 8.2-Release , approx 4000 users ( real ) often running 1000 imap processes.
how does Dovecot 2 compute machine's load ( if it does ) ?

Well, that's definitely one reason why it's working slower. You didn't have to do it.

OK , does Dovecot2 convert index files when starting for the first time or does it use the same ? http://www.esiee.fr/

Dovecot v2 index files are (mostly) compatible with Dovecot v1 index files. There is no "conversion".
