I am trying to troubleshoot poor telnet performance over our WAN, and have come up against a figure for re-transmits that I consider to be too high.
Looking at the device, the re-transmits are currently 7.5% of all segments sent. I have looked at another device to try and get a feel for an acceptable level, and see figures of <1%.
My question is : Is 7.5% too high and very likely to be the cause of my poor performance, or have I just happened to stumble on a really good connection running at <1%.?
Any help is appreciated.
