Problems:

• A lot of rps causes the page to freeze, probably due to the same issues as Tap page often freezes #1597, but top also does additional aggregation, so we should check that the fix for Tap page often freezes #1597 also helps here. Might need some additional work to speed up top's aggregation.
• New data will be inserted into the table very rapidly, so we need to figure out how to order new rows/incoming data so that the order of data in the table isn't jumping around
