Easy ways to irritate me on StackExchange sites (whether my own question or someone else's): 1. Downvote without a comment (N/A if someone already left a comment and you just agree with it, of course); 2. Answer in comments. Other than that I'm a really easy-going and pragmatic guy :-)

@fena22 Edit your question to show the code you've tried (rather than putting it in a comment). Also, if you can show a little bit more code (e.g. what exactly is w in each case). You might also want to say how much memory java is running with.

comment How to calculate the mean of those columns in a data frame with the same column name
Your solution maintains the rownames, whereas joran's drops them (easy enough to re-assign at the end, but the time spent re-assigning them ought to be in the benchmark, for fairness). (Davide's solution also maintains rownames.)

comment R H2O with 32-bit java
I think it would be useful to say which OS you are using. (I'm curious why you don't just use 64-bit java; at least on Linux, there is no issue with R and H2O and 64-bit OpenJDK.)
