What's the problem? Describe what went wrong in few words.
As soon as the initial logos show up the game performance is around 6-8 fps.
Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?
Tested on several versions after 4555, 4589, 4654, 4869 and all of them present the same issue
Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
Yes,4549 and below run the game just fine at stable 60 fps all the time, this issue only happens with muramasa as other games run just fine.
What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
Core 2 duo e8500 3.2 GHZ ATI HD 5450
Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

This seems to be another case where a game is turning on bounding box and not really using it for anything useful. Thus, we're emulating it now, but it's slower because you have an outdated/slow GPU.
degasus, we probably just need to add a switch to turn on/off bounding box emulation.

Seems like Muramasa is clearing the bbox per frame but don't read it at all. Maybe we should update the heurisitic? Or just enable bbox at all on the first read?
