We are completely customized and using AR Server version 7.00.01 patch 001 on Unix. Our Email Engine took about 13 minutes to send 1,000 email messages which is too slow for our customer base. I opened a ticket with BMC who made some suggestions which slowed down the email engine even more, 20 minutes to send 1,000 messages.

Here is what BMC recommended:
Anyway, below are the parameters you can define in the emaildaemon.properties that will help email engine performance. If you make these changes, the email engine must be restart for the change to take effect.

There is some performance tuning that might help your email engine performance.

1. increase this value from 2 to 4

com.remedy.arsys.emaildaemon.NumberOfSenderThreads=2

2. change this value from 100 to 200

com.remedy.arsys.emaildaemon.OutgoingConnectionRecycleSize=100


3. change the polling interval to seconds

Also, if you currently have one mail box moving your notification to another mail box can help the performance as well



Is there anything else we can do to improve email engine performance?

Thank you,
Teresa

Hi,

Then is one more option where your increase the perfromance of email engine, what BMC has mentioned is correct but in added to that please try this one also.
Steps:
1) Go to email.daemon properities file and edit the timing, by default it'll mentioned as 30 so reduce this 30 to 1, this will definetly increase the performance of the email engine. If you made the changes according to what I've mention the cache timing will decrease from 30 minutes to 1 minute. Hope got this point.

Thanks,
Jimmy.
