Hello,
I am on 21.01 version and looking to understand the memory allocation around
API tracing. I’ve got both Rx and Tx API trace enabled. The heap memory is
continuously going up which, I guess, is expected. “nitems” is configured to
1024 which is the default. I do see that the trace wraps a

I am looking to understand a recent observation after upgrading to 21.01
version. Below are the outputs of top command for 19.08 and 21.01 versions and
it seems that the memory footprint of “vpp_main” has increased in 21.01. Is
this normal to be seen with the new version ?

Looking to understand the behavior of NAT in deterministic mode. The issue is,
while in2out translations work fine and sessions are being created

I have been running performance tests and have some questions on the

Hi Everyone,
I am working on measuring the performance with a xconnect of two
sub-interfaces. I did see quite a few performance related questions & answers
in the community which were very helpful to get to this point. However, I’m
still facing rx and tx queue drops (“rx misses” and “tx-error”)
and the
‘flags’ has ‘SUBINT_CONFIG_VALID’ set. Since, by default, physical interface
forwards untagged traffic, is the physical interface itself is being treated as
untagged sub-interface ? is my understanding correct ?
