When I ping ping system a from system b; I get an avg of 1.494ms. When I ping system b from system a; I get an avg of .896ms.
I ran a test my pinging once every 10 second for 1.5 hours. I ran this on both machines. I then re-ran the test several times over 6 days at different times and for different lengths of time. In all cases, pings from b->a out performed pings from a->b by 20% to 50%
I then tried file transfers from a->b and b->a. They varied by less than 5%.
These are identical Linux RedHat servers. Same hardware, same software.
I fully understand that if I were a normal well adjusted person that wasn't obsessive and anal retentive I would have shrugged my shoulders and moved on after noticing the first discrepancy. But I am totally maddened by this.
What on earth could be causing this and how would I check if that is the case?
