My emails are halting or sending very slow.

[nowshow +]

Recently, I used Interspire Email Marketer to send fifty thousand email, where each mail has about 33k.
When I sent the email, the email loading of the system has very slow.
And then I tried to send a small email, about 1~5k, and the sending speed was normal.
Last month I sent the email that also have fifty thousand email that about 33k, and the speed was normal.
I don't know why the Email Marketer became to slow this time.
Could you tell me how I need to configure Interspire Email Marketer?

A lot depends on the MTA solution you are using. Also the configuration of your MySQL environment will make a big difference. Plus , the setup for sending via Cron jobs.
