I did a quick heap profile using -hy:


View it using hp2any-manager (it seems hp2ps only shows one part of
the profile).

I killed hackage-mirror and hackage-server when the resident memory of
hackage-server was over 1GB. At that time it was uploading packages
beginning with 'b' (so there were still a lot to come).

According to the profile most space is used by ARR_WORDS (which is the
internal name for a ByteArray# if I remember correctly).
