The visible advantage to using Cache Agent is the improved speed of file check-out operations. The more files you check out, the more advantage you will gain from Cache Agent. Over time, more and more of the files will come from Cache Agent, reducing the strain on StarTeam Server. As a result, the check-out speed should continue to improve until all files are available from Cache Agent.
For a particular check-out operation, you can see how many files are being sent by StarTeam Server directly and how many are being sent by Cache Agent, by displaying the check-out statistics.
After the check-out operation completes, the Check-Out Statistics dialog box opens displaying the elapsed time, total number of files, total number of bytes, and whether any of the files were failed or skipped during the check-out.
