Thank you very much for your quick response.
As you suggested I changed the chunk size i.e. LG_CHUNK_DEFAULT value
from 22 to 20 , But still the speed performance on MIPS target with
jemalloc not improved.
My current configuration is as below:
I also come across the following thread
"Integrate upstream jemalloc optimizations", here you suggested to Remove the
red-black trees which improves the allocation speed. It means adopting
the fix in the patch improves the performance.
Please let me know if my understanding is wrong.
