MB 3.0.6 Exploit Protection - Opening 400k MSWord file with embedded equations takes 50seconds, eats CPU


Recommended Posts

It took me an insanely long time (around 50 sec) to open what should be small word files.

I took a measurement using WPR and it appears MBAE engine is the culprit.
Admittedly the file has a lot of embedded objects (equation objects) but this is insane.

When I disabled MB Anti-Exploit in the settings, loading the file took 3-5 seconds.

See how 90% of the time of the thread is spent inside mbae64.dll, and that it takes 25% CPU (ie, an entire CPU thread)
