In the following comment https://github.com/JuliaData/DataFrames.jl/pull/2612#issuecomment-776914558 I have code and results of running it that I do not understand. Some calls to
innerjoin function cause 90% GC time, although I know they should not. I try to avoid this using
GC.gc() earlier, but it does not help.
@nalimilan - who do you think might help diagnosing it?
