Dictionary performance is still slow from what I can't tell. Like 2x slower than Python last time I checked.

I also find the dataframe library to be much harder to use/not much faster than pandas.

Great community though.

Right now, DataFrames is handicapped by problems with how DataArrays was designed. With some revisions coming in Julia 0.4, it should be possible to fix a lot of the worst problems (esp. performance) with DataFrames.

The combination of DataFrames and multi-threading will be really amazing, when we get there. I personally use it quite regularly for production work, over pandas - and as John says above, with Julia 0.4, DataFrames will be much better.

I think that being not faster than Pandas is pretty good, since it is written in C and heavily optimized.

The dataframe dev is really responsive though. We worked through a bug together a few weeks back. Nice experience overall.

Something I love about Hackernews: the dataframe dev actually wrote a sister post to yours (John Myles White).
