Mark, Thanks for this data. This means probably simple messenger (not OSD core) is not doing optimal job of handling memory. Haomai, I am not that familiar with Async messenger code base, do you have an explanation of the behavior (like good performance with default tcmalloc) Mark reported
? Is it using lot less thread overall than Simple ? Also, it seems Async messenger has some inefficiencies in the io path and that’s why it is not performing as well as simple if the memory allocation stuff is
optimally handled. Could you please send out any documentation around Async messenger ? I tried to google it , but, not even blueprint is popping up. Thanks & Regards Somnath From: ceph-users [mailto:ceph-users-bounces@xxxxxxxxxxxxxx]
On Behalf Of Haomai Wang COOL Interesting that async messenger will consume more memory than simple, in my mind I always think async should use less memory. I will give a look at this On Tue, Oct 13, 2015 at 12:50 AM, Mark Nelson <mnelson@xxxxxxxxxx> wrote: Hi Guy,
