User's that had issues with MBAR and Processlasso: fix


Recommended Posts

This is just a update to the high CPU% some users were seeing when running MBAR and PL .

With newest version of MBARbeta(8, v. + Processlasso , user should not see a difference with CPU% running both, as was reported before.

I only posted this new post cause old one was locked.

Thanks Ed!

Indeed, this was an important discovery. I traced the CPU usage to a frequent OpenThread API call that (apparently) MBARW hooks at some level, and resolved it by removing the affected code and replacing it was superior code that didn't need any API calls.

Really, nobody is to blame. We had a high frequency of OpenThread calls, but it never mattered on systems where no hooks are inspecting these calls. Likewise, security software is doing it's best to keep the system safe, so has to watch everything, thus the inherit overhead. Though, as I always say, although you should not run w/o security software, there is no replacing common sense when it comes to safety!

This boosts the performance of Process Lasso with any security security software that is hooking the OpenThread API.

We've confirmed the fix, and if the prior topic was re-opened, could state such there so everyone has a final resolution. @Mods?

Attached is the final profiling image where I discovered the issue.
