Any easy performance data exploration programs?

I'm trying to optimize some software, so I generated a large volume of real world performance measurements - nothing fancy, just a few numbers describing the case plus time in milliseconds.

I did some basic analysis on it - mostly dividing data into buckets in various ways and calculating bucket averages - and it was quite helpful in giving me a general idea, but it seems these开发者_StackOverflow社区 relationships are more complex than I expected.

In the mean time I'll keep throwing various formulas at the data, but perhaps by some chance there exists a tool I could use to explore such data visually, and look for patterns this way? Any recommendations?

If you are willing to spend some money, Tableau and Spotfire are good at visualizing data of practically any kind.

I like Excel for this sort of raw data performance analysis. Dump your raw data into a .csv file, load it up in Excel and from there you can group and graph the data however you want. Once graphed, often discernible patterns will emerge.
