We have been looking at the performance of a group of web servers and there are two TCP error types which are looking troublesome, but not sure what the acceptable rates would be.
For the bunch of 8 servers, the RST levels (client end only) for the 3 busiest servers are running at 12-15% of the transmission rate, the others are running at around 8%
The same 3 severs also have between 3-5% client end Zero Windows as well. On investigation the PCs (its a College) are all quite old and Wins 7 has been shoe horned onto them so I’m putting this down to lack of resources on the PCs slowing the data transfer, but I’m not sure if this is related to the RST levels directly or not.
The description of the RST is a forced termination of the session, possibly page not loading and or the users giving up, but are these levels excessive and can this be related to the Zero Windows or is this something else?
Any thoughts would be welcome
