#671 Execution slowdown when TAM enabled
Fixed, last edited by Jarvis last edited by Jarvis
0.- Install VLC 3.0.4 x64
1.- Enable TAM
2.- Open an audio mp3 file
3.- VLC takes more than 30 seconds to open and start to reproduce the mp3 file
4.- If You close VLC and try again, will open fast, but with every new session, or in the same session after some time, again You may get slowdown execution VLC.
I'm not getting this behaviour with all applications + TAM enabled, but probably it is reproducible with others.
I already reported this behaviour some years ago during beta testing of previous build of Kaspersky KIS/KTS.
VLC takes more than 30 seconds to open.
VLC should open in about 1 ~ 2 seconds.

Ok, this is the 1st delivering, includes:
* Full TAM traces during enabling/analysis.
* Xperf debug traces of 1st VLC execution after TAM enabling.
Will collect more traces to reproduce "long time" slowdown soon...
Traces (1,3GB compressed of more than 19GB of raw data): https://cloud.qainfo.ru/s/Rx5GSL20lHmsi7V
Developers ask for full traces from the very beginning:
1 Please, set traces to maximum level
2 Enable TAM (let it finish software analyze)
3 Start xperf (only after TAM is enabled)
4 Open mp3 with VLC
5 Please, try to reproduce "long time" mp3 start for second time ("...every new session, or in the same session after some time...")
