Re: Optimizing Lua memory access/usage...

["J. Perkins" <jason@...>]

A very generic solution is to write your own memory allocation
routines and pool small requests together into larger pages. I
haven't gotten around to writing one for my current project, but
there is a good example in the Nebula Device at Radon Labs:

Besides significantly reducing fragmentation, this also gives
a decent overall performance boost. Of course, this is more of
a workaround than a real solution.
