Hello,
I have configured Secure email gateway, configured Local Tracking for Email message tracking. When we use message-tracking API to get the email messages, API gradually taking more time when index increases. eg: for messages 1-100 it is taking 1 sec then 101-200 it is taking 2 sec like wise for 1001-1100 it is taking 6 sec.
I have 5000 email messages, to get all the messages it is taking around 8 min 50 sec. is it expected behavior in gateway API or any other way can increase this time/ best practices to avoid these latencies.
