New Revision: 42340
Changeset: https://dev.haiku-os.org/changeset/42340
Modified:
haiku/trunk/src/system/kernel/port.cpp
Log:
Optimize the configuration of the port heap. Previously the max bin size was
512 bytes with a heap page of 2048 bytes resulting in excessive waste for
allocations between 512 and 1023 bytes. Also tune the requested alignment so
that sizeof(port_message) (currently 28 bytes) can occupy one allocation unit
without waste.
