Timing of NetworkTables

[Thad House]

Today I was trying to test the Latency in our system, and I set up a loopback test between the CRIO and our DS/Beaglebone. Using NetworkTables, I was seeing anywhere between 100-200ms of latency between sending and receiving. This seems really high. When I try pinging, it says it responds in less the 1ms, so its not the connection. Has anybody else tested this, or have any documentation on what the latency for NetworkTables is?

Also, I was trying to set up this test with UDP, but I could not get it to ever work. Has anybody else tried testing the latency of UDP, and if so how'd you actually get it to work.

Thanks
