[Mailman-Users] Performance Issue?

[Trevor Dodds]

Hi,

I have a list of 5000 users, this is a newsletter only list and is currently the only list on our server the server has lots of free memory and cpu does not run high. The problem I'm faced is that when an email is sent to the list it takes a while before mailman starts sending the email to sendmail. This process took over 2 hours.  Is It normal for mailman to send bunches of around 300 users per mail shot? Is there anything I can do to speed up email between mailman / sendmail?
