High connection time from the tool

I was running a load test using a tool on an internal application and observed that response times are very high. When i manually tried accessing the application from the test system, it took comparatively very less time to display pages. After test i analyzed results and found that the connection time is almost 60% of total response time for the transaction.So can it happen that the connection time is high when we access the application from a tool while its less for a browser.

If you are seeing high times when running a load test, it is probably because your server can not accept any more incoming connections and the client is having to re-try. That’s one of the things you end up testing when you run a load test. When you manually access it, was the load test still running or was the server idle?

When i manually accessed the application the test was going on.
