We're relatively leisurely. We have players who can tag several times a day and players who can tag every day or two. We have a timeline post to sort out what has happened when, which is a good primer of what we've done so far. Currently, Jon Snow has made it to King's Landing and negotiations with Daenerys are ongoing.
In terms of tag length, again, it's relative, but the standard seems to be about three paragraphs per tag. Given that standard, it does take multiple days to finish threads, rather than doing it quickly in a day. If you have any issues with pacing, though, just talk to the mods (~warg, ~porcelains) and I'm sure they can sort it out.
