We can test this. In HeapImp.h, there is HPAGE constant. This is the size of "master chunk" (in 4KB units) and also maximum size of block that allocator keeps for reuse. Try to change that to something smaller, like 256 and retest...

Mirek

In case of HPAGE = 256 it is starting to use tens of gigabytes in just a few seconds ...


Now that is an excelent clue Smile

Found and fixed a bug (stupid one really). Can you test now please?

Mirek


HPAGE = 256
ram: 308 Mb, time: 253 s.

HPAGE = 7 * 8192
ram: 714 Mb, time: 232 s.

StdAlloc still remains the best choice for MT ...
