Hello everyone,

I install G'MIC-Qt 2.5.7 in GIMP 2.10.10 (operating system is Windows 10). In my image editing process, I use a lot of Smooth [wavelets] filter. I notice that it runs slowly (like 1 minute for 24 MB tif images). I just want to know, is there any way to make it run faster? Does it help if I increase the RAM or something? Or maybe do you guys know another noise reduction filter in GIMP that has the same quality but runs faster? Thank you for your help.

Hello everyone?

You might want to contact G'mic developer on this. It may not be optimized for your system. It's not too slow here, but I'm running Linux and it's usually faster than windows.

Hard to tell without hard data. Use your performance monitor.

If the CPU maxes out while the filter runs, then you have a problem of CPU (and nothing will help, short of changing the CPU).

If you RAM is all used and you have significant swapping, then either get more RAM, or close a few RAM-hungry apps (browsers...).

If the RAM doesn't seem all used but there is some disk I/O, check in Gimp Edit>Preferences>System resources that the "Tile cache size" is set to something adequate (at least half your RAM is you aren't too RAM-constrained).

I ran that filter on a few images today, most were 1920x1080. It took about 5 seconds to complete here on my desktop (i7) with 12 GB RAM running Linux Mint 19.3 - Gimp 2.10.12 and G'mic 2.8.0.

In my tests, it's all CPU and very little RAM is used by this filter.

Hi Hanciong.

In addition to the computer parameters, the G'MIC version is also important.
Other users say that G'mic 2.8.1 improves performance (especially for Windows - because Linux doesn't have these problems) and is much faster than very old 2.5.7 (which You use ???).
