Hi Pim,
The defaults we use are 96M for stat segment and 1G for main heap (default
main heap size). I know these need to scale up as the numbers of routes
and/or threads increase. These values can accommodate a million routes or
so when running single threaded, but allocations on the stat segment
Hoi Matt,
Out of curiosity how large is your heap and stats segment? I ask because
running VPP with a large FIB I needed 2G heap size (and I used page size of
2M), and 96M of statsseg:
memory {
main-heap-size 3G
main-heap-page-size 2M
}
statseg {
socket-name /run/vpp/stats.sock
size
Hi all,
It's my understanding that when you set the size of the main heap or the
stat segment in startup.conf, the size you specify is used to set up
virtual address space and the system does not actually allocate that full
amount of memory to VPP. I think when VPP tries to read/write addresses
