Hello Anbu, happy new year --

The general problem is that Performer's shared arena must be a contiguous
block of memory; but various system libraries (mostly Performer's) are
sprinkled around in memory to the point where it's difficult to get a very
large region.

The good news: we've fixed this in the final Performer 3.1 images. These
will be available in days.

In the meantime:

 - Besides PFSHAREDSIZE you can also experiment with different values for
PFSHAREDBASE to get a lower starting point than the default.

Otherwise you (or we) need to remap your Performer libraries into different
locations in memory, hopefully more tightly packed together.

 - We ship a tool /usr/share/Performer/src/tools/remapLibs which can do this
for N32 and O32 applications. It maps them into high memory.

 - If you are an rqs expert: remap your N32 libraries to this location:
                :st = $range 0x02000000, 0x08000000:
   N64 libraries:
                :st = $range 0x02000000, 0x0b980000:

That's relatively low memory. This is what we've done for 3.1.
