Animated GIF killing magick

[mgo]

Hi!

Out customer uploaded a 1mb GIF file, which on command "-coalesce" causes the RAM usage to peak at 9GB and takes around 40seconds to process.
It looks like a magick bug (other tools handle it well).
Below is link to the aforementioned file:

On our host, the conversion completed in 3 seconds. We're using ImageMagick 7.0.8-64. Your system may be thrashing. Try this command instead:

Code: Select all

magick convert -define registry:temporary-path=./ -limit area 0 m3-zinsen-gif.gif -coalesce coalesce.gif

Dear Magick,

I will try upgrading. I was testing on 6.9.10-62 Q16 x86_64 & 7.0.5-4 Q16 x64
I tried the command and for me it reduces the RAM usage to 100-200mb level, which is very good, but it still takes siginificant amount of CPU (and takes a long time).
Do you think that setting the temp directory results in reduced RAM usage?
I will get back to you once I updated. Thanks for helping out!

Updating did not make any effect. System is equipped with SSD. I wonder how can you achieve 3 seconds when it takes 30-40seconds for me. Other GIFs take 1s to process, but not this one. I'm trying both Linux and Windows versions.

Can it be ImageMagick configuration?
I'm pasting the config:

One difference is OpenMP support. We have a 6 core processor with 6 hyperthreads. With the OpenMP feature enabled, 12 threads are run in parallel when coalescing. Your slow-down may come from thrashing and also running in a single thread.

[mgo]

Yes it's possible. Thank you!

[mgo]

Sadly, enabling OpenMP did not make a difference. Problem must be elsewhere.
