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.

Subject: [vpp-dev] memory issues
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:
