This seems the same as bug 98500 (the summary says "multiple", but description speaks of slowness even with 1 gif)

*** This bug has been marked as a duplicate of bug 98500 ***

Not so fast.. as you repro the behavior already in 4.4, it is different from bug 98500.

For me, CPU is not exactly maxed out, but it does double.

Yet, Armin's comments in bug 98500 still hold..

Not sure how useful this report is anyhow. There is no actual problem here and the CPU part is already (indirectly) covered by different bug reports.
