Application is running very slowly on OS/2 - not on other platforms. #28

Describe the bug There is application - RSS Guard - which "has" support for OS/2. I am the author.

The application seems to overally run very slowly on OS/2.

Here is sample from logs, which slows it down (it stays for +16 seconds "frozen", not sure in which part).

I suspect that (given the logs) this might be related to how QtWebEngine module is ported to os/2.

It was seen on some of last versions of ArcaOS.

I wonder which platforms do you refer to here in particular and how exactly do you compare the "speed"? What is the configuration of the OS/CPU/GPU/Mem/Arch of the platforms you are comparing it to? It would be simply incorrect to compare a 32-bit platform with a 15-years-old CPU and no GPU and only 4 GB of memory (or it's software emulation running in a VM) with a bare metal 64-bit platform with a modern CPU, modern GPU, 32 GB of memory, SSD etc. Of course, the latter will be faster than the former in almost every way.
