IBM MQ V9.3 Performace using Windows Defender AntiVirus

    Hi All,

    I am currently working for a client on an MQ V9.3 Multi instance deployment on Windows 2019.  During a performance/load test we have observed a significant performance overhead with Anti-virus software (Windows Defender).  This is not an IBM MQ Product issue, but looking to see if anyone has any experience in tuning Windows Defender including things such as file exclusions etc.  Possibly somebody is aware of a TechDoc?

    Hi Mark, 

    We were in similar situation and using file exclusions. It's only been a day after we added the file exclusions. Here is an article about the exclusions from IBM.
