Cached load test results

For the cached load test, see Figure 4. The first part of this report shows the slowest Avg. page time, which is more than what we saw in the non cached results. This makes sense when I think that the first time the page is loading, all the caching is happening. This would explain the differences. 

Figure 4: Cached Load Test Summary

When we look a little deeper, this is where we see the benefits of caching. For instance, if we look at the average test time for AllCachedReports, the number is 412 sec. For nonCached, the number was 559. This appears to be a 30+% better performance. When looking how many tests were run, for AllNonCached, 40 tests were run.

Looking at CustomerCached, the average test time was 96.5 sec. In the non-cached version, it was 87.2 sec. So it appears that for some reason, caching was not helpful for this report. But the gain in noncached was around 10% in this case. When looking at how many tests were run, 14 tests were run for CustomerCached. It appears that the gain from AllCachedReports allowed CustomerCached to be run more times.
