A company that I work for is having some WAN performance issues. We have some branches that respond with 25 - 70 ms response time they are around 150 to max 200 miles in distance. It seems as though the performance issues follow the slow ping response times.
The ISP recently switched over to a different frame-relay switch for the DS-3 coneection we have. In this switch over we upgraded the bandwidth. Now we are having performance issues. The branches are much slower AT TIMES. Whenever we transfer a file to the branch everything else dies and slows way down.
Any advice on how to troubleshoot this and find where the issue is would be appreciated. The ISP is looking into it but have not came to any conclusions.
Thanks
