Terrible Magento backend performance caused by AheadWorks and Magestore extensions

I was troubleshooting an awful Magento backend performance and it turned out to be caused by 2 extensions from AheadWorks and Magestore: Magestore_Magenotification and AW_All (AheadWorks). I’m surprised to see such problem from 2 major extension-companies. I suppose these extensions are not essential and are just being used in the backend.

Using mgt-commerce’s profiler I noticed this problem. Disabling these extensions got the load time down from almost 20 seconds to 2.37 seconds.

Disable them in these files;
app/etc/modules/Magestore_Magenotification.xml
app/etc/modules/AW_All.xml
