to confirm the way, i did below test (both udp and ipc works fine):
java -cp samples.jar \
-XX:+UnlockDiagnosticVMOptions \
-XX:GuaranteedSafepointInterval=300000 \
-XX:BiasedLockingStartupDelay=0 \
-Dagrona.disable.bounds.checks=true \
io.aeron.samples.LowLatencyMediaDriver

java -cp samples.jar \

-Daeron.sample.ping.channel=aeron:ipc \
-Daeron.sample.pong.channel=aeron:ipc \
io.aeron.samples.Ping
and the IPC latency max 25us while 99.84%<5us (without any os parameter
trunig).
but when i run two ping process with one pong using udp, seems two ping
processes cannot distinguish each other, any advise on this?(something
like more client want their own response)
Thanks again.
