# Do a direct lookup of all possible text keys, and figure out which ones
# are actually present, and then convert it back to revision_ids, since the
# file_id prefix is shared by everything.
- # Using a set of revisions instead of a set of keys saves about 1MB (out of
- # say 400). Not a huge deal, but still "better".
+ # Looking up keys in batches of 1000 can cut the time in half, as well as
+ # memory consumption. GraphIndex *does* like to look for a few keys in
+ # parallel, it just doesn't like looking for *lots* of keys in parallel.
