Email Logs not clearing - The process to send emails seems very slow.

Diagnostics done at the client's site showed the following:

1. The client had 28000 active users. The Email scheduler needs to check if the Email address allocated to the user is valid and that the "Unsubscribe" list is activated. this was causing significant delays
2. There were over 5000 emails in the queue. 
3. Email Send Restriction was set to "50" per minute

We will investigate further and see how we can improve this.

2. The following changes were made(Include Database object names, Program classes, and any other relevant information):
