The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

DS3 dedicated pipe will not do 45Mbs will only go 4.5Mbs per stream

Asked by CyprexxDev in Network Routers

Tags: DS3 IPS 45Mbs slow

We had a DS3 installed at two locations a basic MPLS ring or could call it a DS3 IPVPN pipe. Either way If we iperf end to end, we only get 4.93Mbs at best if I copy a 10mb file sit take 30 seconds. The isp claims that if I do the Iperf with 10 connection at one time the latency does not drop and the speed totals 40.4Mbs I find this close to snake oil. What speeds should I expect on a DS3 45Mbs copyig a file from ssyetm to system. (I have done TTCP from router to router and get teh same 4-7Mbs througput) Below is the Iperf for 10 connections at one time, even with only one I never get past 7Mbs.
