I have two sites with 1024k links in UK. The links behaves as if they are rate limitted even though i dont have any rate limitting set on the router. The customer for instance sent a 3meg file from a site locally to the UK site. it went up to about 900k and then while the file is being copied it went down and flacuates between 400k and 600k. Can someone advise what to do ? I tried using test tcp the telnet session times out before I can get any results. i dont see much traffic on my WAN interfaces as well.
