Re: archiving speed [was Re: Tips on maintaining history in Org Mode]

[Samuel Wales <samologist@gmail.com>]

thanks for the clarification.  are you saying that, for every archived
entry, it calculates teh category property, using the original org
file, in order to add a category property to just one archived entry?

that would certainly slow down more and more, but it sends me back to
my question about whether append to file would work.
i.e. build the single entry in a temporary buffer then write that
region to a file on disk.
