Hi all,

We are working on a system which requires allocating a big number of mem zones.

We are now reaching the max limit of MEMZONEs allowed (RTE_MAX_MEMZONE). 

I see today dpdk limit the above number to 2560. 
Is there any specific reason for that? can I increase it in case needed. What may be the side effects of such changes?


Thx
Nissim

You can increase the number of memsegs, 256 is just a default value.
The only side-effect I can think of, on systems that use more than the 
default number of memsegs, is slower EAL initialization and increased 
memseg lookup time.
