ok so what can be the reason?
if I stop dovecot, the load fall down to about 0.3. if I start dovecot 
and about 50 people connect to it it goes up to 3.x-4.x. which actualy 
irritate me and the samba server stops for a few seconds for every 10-20 
minutes and it took about 20-30 second to delete a mail in mozilla an 
show me the next (simple text) messages.
any tip?
how can I test it or help to you to find out the reason?
it there any way to measure the total amount of read and write issued by 
all dovecot process? or...?
