Allocating a large number of 16 byte objects @ 64 byte alignment will never
work very well. If you pad the
calculation might be a brick shy of a load.

+1.
It would be super-helpful if you were to add test cases to
.../src/vppinfra/test_mheap.c, and push a draft patch so we can reproduce / fix
the problem(s).
Thanks... Dave

Dear Kingwei,
We finally managed to look at your mheap patches, sorry for delay.
Still we are not 100% convinced that there is a bug(s) in the mheap code.
Please note that that mheap code is stable, not changed frequently

Hi Kingwel,
After I merged the three patch ,there is a SIGSEGV when I startup vpp (not
every time). And the error didn't appear before .

Hi Damjan,
We will do it asap. Actually we are quite new to vPP and even don’t know how to
make bug report and code contribution or so.
Hi Kingwel,
Thank you very much for your help.

Dear Kingwel,
Thank you for your email. It will be really appreciated if you can submit your
changes to gerrit, preferably each point in separate patch.
That will be best place to discuss those changes...

Hi all,
We recently worked on GTPU tunnel and our target is to create 2M tunnels. It is
not as easy as it looks like, and it took us quite some time to figure it out.
The biggest problem we found is about mheap, which as you know is the low layer
memory management function of vPP. We believe it

Hi Dave,
The perf backtrace (taken from "control-only" lcore 0) is as follows:
- 91.87% vpp_main libvppinfra.so.0.0.0[.
Hi Ole,
I need roughly the amount of tunnels I ended up testing with - ~300-500k.
I thought about extending generic VPP API with a (blocking?) method
accepting burst (array) of messages and returning burst of responses.
One of the challenges in map is that to configure a tunnel I need two

Jacek,
It's also been on my list for a while to add a better bulk add for MAP domains
/ rules.
Any idea of the scale you are looking at here?
Best regards,
