 Hi,
For serveral days, I did some test about the memory performance of glibc(2.17) and tcmalloc(gperformance 2.7), and my test results indicate that glibc is more efficient then tcmalloc. generally, people think tcmalloc is efficient than glibc 2.3, but I use glibc 2.17, so I wonder if glibc 2.17 did some improvement on memory performance.
 looking forward to your reply, thank you.

You may also want to check out my proof-of-concept wfcqueue patch
which optimizes message passing:

https://public-inbox.org/libc-alpha/20180731084936.g4yw6wnvt677miti@dcvr/

Unfortunately, integrating wfcqueue/URCU into glibc will take
much effort :<

Also in future, I think, "restartable sequences" should improve malloc performance, right? I'm wondering, when will they appear…
