I was just looking at some stats on the average time our customers' servers take to run our application test suite.
I noticed on a particular day the times dropped from an average of 240 seconds to an average of 200 seconds. (These are averages from about 240 customer sites.) The numbers are generally quite stable so I was curious what changed.
I discovered that was the day we updated everyone to the Java 8 JRE so it looks like that's the reason for the improvement. Assuming that's the correct explanation that's a pretty nice upgrade!
It made sense that it was Java related since customers running the older cSuneido did not show any improvement that day.
Note: jSuneido is still compiled for Java 7, this improvement would just be from the runtime.
