Have you ever compare the GSlice allocator with other malloc library

I'm not aware of any such benchmarks or comparisons, but it would
definitely be interesting to see some!

Also, as far as I remember, GSlice is pretty much a straight-up
implementation of Bonwick's slab allocator plus the subsequent changes
for using magazines for threading/multicore performance.  I don't think
GSlice has been updated with all the work that has been done in e.g. the
Linux kernel for slab-like allocators.

(Also, GSlice doesn't really use all the features of the original
slab/magazine allocator - for example, blocks of memory are not recycled
by resetting them to a "just initialized" state; instead, blocks are
freed and re-allocated / re-initialized as needed.)
