Noticeable, and very pleasureable.

data _ Bitmap new: 1000.
1 to: data size do: [:i | data at: i put: 10000 * i].
m _ StarSqueakMorph new.
Time millisecondsToRun:
         [10000 timesRepeat:
                 [m primEvaporate: data rate: 75 * 1024 // 100]]

Sans plugin: 4686 ms, with plugin: 40 ms.

Or the massive

src _ Bitmap new: 10000.
src at: 5000 put: 20000.
dst _ Bitmap new: 10000.
m _ StarSqueakMorph new.
Time millisecondsToRun:
         [m
                 primDiffuseFrom: src
                 to: dst
                 width: 100
                 height: 100
                 delta: 50]

Without plugin: 20700 ms, with plugin: 130 ms.

In ant colony terms, with the plugin, two colonies at 500 ants each run at 
about the perceived speed of one colony of 500 ants without the 
plugin.  Two AntStones vs one...

HTH,
