Ubuntu 22.04+ perf issue

Describe the bug

secnetperf results from 22.04 and 24.04 are slower than that of 22.04.

Both physically separated and local VMs have similar problem
HPS/RPS tests are significantly slow (tested locally)
Throughput test is unstable. sometimes fast, sometimes not
Tried sysconfig change (buffersize etc.). slow
NIC config doesn't affect (GRO LRO are on by default)
Tried Both openssl and openssl3. slow.
Tried disabling AppArmor. slow.
Server Ubuntu22.04+ and Client Ubuntu20.04 is slow
Server Ubuntu20.04 and Client Ubuntu22.04+ is enough fast

Server side QUIC handshake related part become slower when Ubuntu22.04+?

Steps taken to reproduce bug

# Server
$ ./artifacts/bin/linux/x64_Release_openssl/secnetperf -exec:maxtput -io:epoll -pollidle:10000
# Client
$ ./artifacts/bin/linux/x64_Debug_openssl/secnetperf -target:172.25.246.35 -exec:maxtput -rconn:1 -share:1 -prate:1 -tcp:0 -trimout -watchdog:25000 -pollidle:10000 -run:12s -io:epoll -conns:100

Expected behavior

both should be similar perf

Actual outcome

1/3 - 1/10 slower HPS perf
