I agree 5g is large, but I do not think this is the FIB. The default heap maxes out much sooner than that. Something else is going on.
For DPDK, “show dpdk buffer” and otherwise “show physmem”.

Hi Chris，
I see what you mean. I have two other questions:
1. 200k static routing use 5g memory is also large , how can I configure it
use less physical memory?
2. How can I check the packet buffer memory?
BTW, do you have the test similar with 'the memory size 200k static routing
use'?
Thanks,
Xyxue

You’re misreading top. “Virt” only means the virtual memory footprint of the
process. This includes unused heap, shared libraries, anonymous mmap() regions
etc. “RSS” is the resident-in-memory size. It’s actually using 5G.
“show memory” also only shows the heap usage, it does not include packet buffer
memory.

Hi guys，
I am using vpp v18.01-rc0~241-g4c9f2a8.
I configured 200K static routing. When I 'show memory' in VPP, '150+k used'.
But in my machine ,used almost 15g. After del the static routing ,almost using
16g memory.
More info is shown below:
