Delay/Lag after hitting Submit on a Ticket

[tupson]

Overview:

Version: OTRS 3.3.18
Mail Service: Microsoft Exchange 2013 CU15 2 Node DAG
DNS: A record that talks to the DAG IP Address (which is supporting two different Exchange nodes)
OTRS Certificate: Issued an internal Microsoft CA certificate replacing self-signed certificate
Desktop: Windows 10 (1803) 64-Bit (IPv6 NIC setting disabled)

Problem:

When responding to a ticket, after hitting submit - some times the window sits there for up to 60 seconds before it completing the submission and sometimes its instant. Both in Internet Explorer and Google Chrome.

I am trying to figure out why this delay is occurring and if there is anywhere logging this?

3.3. is outdated, extremly unsecure, hackable and not supported since years

I assume you use direct SMTP connection from OTRS, switch to OTRS 6 and/or sendmail (e.g. via Postfix)

Hi,

timouts 60 or 120 seconds are usually DNS issues. So check your network.

I upgraded to OTRS6 on CENTOS7. Thanks for the encouragement to move forward with figuring this all out. Runs smooth.
