Memory usage can probably be attributed to how PHP manages memory (hint: It /almost/ doesn't).

Right.

Outlying results have to do with that whatever that specific benchmark concerns, e.g. thread startup cost.

There are 2 which require threads, there's no PHP program for either of those so why do you think "thread startup cost" has any relevance?

[silentbicycle]

I wasn't stating which the outliers test, I was saying how to read the graph.

If that was your intention it's strange that as an example you suggested something that is not shown on the graph.
