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!

Performance issue when cfc is called as web service

Asked by ckercher in ColdFusion Application Server, Sun Java System Web Server, Cold Fusion Markup Language

Tags: ,

Hello,
We are using Coldfusion MX 7 on a Windows 2003 server SP2, 3Gigs RAM, 4 CPUs (2 dual core), SUN  JVM 1.4.2_11, Min & Max JVM Heap sizes = 512, simultaneous request limit = 24. I created a CFC which does a cfhttp call to a remote SaaS application. Included on almost every page of our website is an iframe that calls the CFC. When I invoke the CFC with cfinvoke and I do not call it as a service it works fine under normal load. I created a web service using this cfc, when I invoke the cfc as a web service the CF process hangs and has to be restarted.

I then downloaded Microsoft's Virtual PC 2007 and in a virtual machjine downloaded MicroSoft's Web Aplpication Stress 1.1. After some testing with numerous simultaneous users settings I found a point at the CF server will hang up and have to be restarted when using the web service. When I change the .cfm to not use a web service but simply call the cfc the CF server does not hang and response from the website is acceptable.

Any suggestions on how to figure out why the web service hangs the server while the same number of calls to the cfc without using a web service is ok? It looks like a JVM issue but am not 100% sure at this point.

Any help is greatly appreciated.
