VM Plugins that are important for performance?

Hi all:

From your experience, what are the important VM plugins to gain a snappy and responsive Pharo image.

Stef mentioned the Font plugin, but will this improve the user experience or is it just nice to have to support different kinds of fonts?

The reason for my question is the 'performance hit' I have to take with the RoarVM for the moment.
So, if there are things typically done in plugins which now running in Smalltalk on the RoarVM, then I guess I could benefit by including those plugins.

Thanks
Stefan

Do you have the MiscPrimitivePlugin?

B2DPlugin
B3DAcceleratorPlugin
BitBltPlugin
FilePlugin
FloatArrayPlugin
LargeIntegers
Matrix2x3Plugin
MiscPrimitivePlugin
RePlugin
SocketPlugin

I doubt any plugin changes the performance of #tinyBenchmarks. But the
following plugins make a huge difference in other benchmarks and GUI
performance:
- MiscPrimitivePlugin
- LargeIntegers
- FloatMathPlugin
- FloatArrayPlugin
- Matrix2x3Plugin
- B2DPlugin

DeflatePlugin is also important. It has a large impact on performance
when using Monticello.

Are you sure about FloatMathPlugin?
I haven't found any usage of it. Neither in Squeak 4.1 nor in Pharo 1.2.

Thanks

Yeah, it's not used at the moment, but it if the primitives are used, then
some codes get much faster without a JIT (I don't know if it's faster or
slower with Cog).
So, you're right, the current images don't need/use it. Therefore it
doesn't make a difference.
