It's also very easy to add latency for testing as well.

Example to add 10ms to ixgbe0 interface:

tc qdisc add dev ixgbe0 root netem delay 10ms limit 200000 and/or tc qdisc change dev ixgbe0 root netem delay 10ms limit 200000

If you do "netem delay Xms Yms" it will do X +/- Yms roughly.

Note that this is on output only, so is typically more useful on a device in between endpoints. Also, don't use it on a high traffic link, it'll have difficulties.

Thank you! I'll have a read about tc as well!
