Try to get a better sample. From a UNIX machine do a sequencial ping to IP
on the GEIP with a one second between each ping, may be you are going to see
that each minute you have a very big response time. For the rest of the time
it´s fine.

We have seen latency without loss on packets to a 7500 GEIP+ interface.
Our interpretation is that IOS did not properly initialize the interface
to generate received packet interrupts. Packets landed in the buffers
and were cleaned out on the next clock interrupt, producing an appearant
distribution of arrival times. Upgrading IOS fixed this.
