Update.

I changed my app. Now it is doing a bunch of string manipulations (mostly concatenations)

Results:
U++:
time: 234s, mem is growing to 4.4Gb and it is not going down till the very end.

glibc:
Default settings (8-core CPU, CoWork pool has 18 threads):
time: 239s, mem max is 6.5Gb down to 3.6Gb

export MALLOC_ARENA_MAX=16
time: 239s, mem max is 4.2Gb down to 2.8Gb

export MALLOC_ARENA_MAX=8
time: 244s, mem max is 4.0Gb down to 1.3Gb

Conclusion:
glibc allocator is more efficient with a little bit of manual tuning. Difference in performance is not that signifficant. Cannot tell anything about Windows.


Regards,
Novo
