I consider growing by 8K is perfect.

Also, as far as I know, perl itself gets memory from system each time twice as in previous memory allocation, and I find this strategy much worse than allocating by some reasonable chunks.

But why you do not use Compress::Zlib or similar modules, or even C interface to compression library (as long as you'r in Inline::C)?
I think this approach will save much more to you and will add portability? (Win32 may not have /usr/bin/compress)
