Hello,
I have the following hw: cpu Xeon(R) CPU D-1533N, nics Ethernet Connection X552
10 GbE SFP+. When configuring vpp in single-threaded mode, ping to a neighbor
is about 0.05 ms. When I try to enable one or more workers, the ping rises to
10.05 ms. Multi-thread mode configuration:
cpu {
main-core 0
corelist-workers 1
}
vpp# show thread
ID Name Type LWP Sched Policy (Priority) lcore
Core Socket State
0 vpp_main 19915 other (0) 0
0 0
1 vpp_wk_0 workers 19919 other (0) 1
1 0
vpp# show int rx-placement
Thread 1 (vpp_wk_0):
node dpdk-input:
TenGigabitEthernet4/0/0 queue 0 (polling)
TenGigabitEthernet4/0/1 queue 0 (polling)
Core 1 is isolated from the Linux kernel.
Htop shows a strange processor usage for vpp_wk_0 - either 66% or 132%. The
same behavior on 19.04 and 19.08.
What could be the problem?
Thanks.
