for tcmalloc do you need master? this recent release seems to have CMake

Of course, I do not mean to force the usage of it. But could be a
suggestion in case we do not find anything better and a user has problems.
Or a way to
I’ve used mimalloc successfully in the past, worth a look if a drop in
replacement for new / delete / malloc / free is desirable. Do note that its
performance is usually uniformly superior to glibc / msvc but there are
unintuitive performance cliffs. Given the block nature of most gdal raster
I've played with VirtualAlloc(NULL, SINGLE_ALLOC_SIZE, MEM_COMMIT |
MEM_RESERVE, PAGE_READWRITE), and it does avoid the performance issue.
However I see that VitualAlloc() allocates by chunks of 64 kB, so
depending on the size of a block, it might cause significant waste of
RAM, so that can't
+1. We use a variety of hand-rolled VirtualAlloc based (for basic tasks, a
simple pointer bump, and for more elaborate needs, a ‘buddy’) allocators, some
of which try to be smart about memory usage via de-committing regions. In our
work, we tend to disable the GDAL cache entirely and rely on
