Disabling tcmalloc cache
coder-saab001 opened this issue · comments
Hi community, is there is some way to disable the tcmalloc cache totally. We are working on minimising the memory usage of our system.
I doubt that any answer given here will differ substantially from the answer given on gperftools/gperftools#1466.
@junyer is correct. The caches hold onto freed objects by design, since they will likely be reused in the future.
TCMalloc has a number of heuristics to find unnecessary objects and flush them, but all of these are designed with a balance for CPU and RAM usage.
