Ok, so after playing with for few days we have realized that Open source edition appears to have performance issues?
We are trying to load test this thing with about 10 emails per 3 secs and its success rate is very low with a tons of time out errors.
What could be wrong here? We are using it on a Blade system with 8 GB ram + 2.4 GHz quad core processors!!!
How do we configure this so it could process large amount of emails?
Thanks for your help.
