ImageMagick slows down over time while processing a large batch of images?

[B_Gaspar]

Hello

I don't know if this is the right place but I'm having a similar issue with Magick running in windows batch file. The batch file starts at great speed, then after about 600 images starts to slow down. I notice that the processor usage also goes down, and from my understanding its happening the same to me. Diferent computers on test same issue.

You are not using Magick.NET, so I'll move this to the Users forum.

pushd \\192.168.0.191\ ...

You are accessing a network. Perhaps this is causing the slowdown. I suggest you try it locally by first copying the files from the network.

If the slowdown is consistent with using the network, use system-management tools to find the bottleneck.

Thanks. A lot. That was my first idea. I will give more info after a few more tests.
