How to make a wine application run on multiple processors

[eric41]

Hallo!I have Wine installed on my Debian 10.5 Buster Linux on an i5 laptop

I am running a heavy Windows application on the wine and everytime the application consumes 100% of one of the CPU cores and stalls forcing me to terminate the application everytime.

Is there a way to make wine applications run on more than one CPU core or use the core more efficiently without hogging 100% of a core?

If the program is programmed to only use one core, there's nothing Wine can do. Sometimes Wine is slower than Windows, but apart from that, you can't "use a core more efficiently".

The program just freezes? Did you try to wait for some time already?

@eric41

The wineserver process is single-threaded and can therefore cause performance issues, by acting as a bottleneck. This holds especially true for multithreaded/ CPU-bound applications.

You can check for bottlenecking, of your application, by using:

Code: Select all

perf record wine ???.exe

to record a performance trace.

The results of this trace (sorted by overhead) can then be displayed by running:

Code: Select all

perf report

The Windows Application that I am trying to run is Metatrader 5.I ran the commands that you suggested ie

Code: Select all

perf record wine terminal64.exe

and producted a report using command

Code: Select all

perf report

that I spooled onto a text file with output shown o link below.I am not a Wine expert so what does the output below mean and can it aid in resolving my issue?

Ahh, that trace output is actually quite interesting! Looks like the (unnecessary) Wine builtin winemenubuilder.exe process is going a bit nuts...

Does it help performance, of Metatrader 5, if you try disabling winemenubuilder.exe?
