Yes I know, but I would perhaps settle for say 5 minutes - otherwise it is
not that useful... :-)
It would probably be better to be able poll a page with a simple timestamp
for the last page saved. That would be much easier to generate on the server
and much less info to transfer.
We actually have a patched swiki at Bluefish where we keep track of which
"recently changed" pages each person have read and a special url where
a short list of those pages can be accessed. That page is much better suited
for this kind of polling (no HTML formatting etc).
By the way, we profiled a bit of the BigTime Swiki generation of HTML and it looked a bit
strange...
It seemed on my first cursory look that the #nextPutAll: method in WriteStream
fell back on super... I will check into it some more but that looked "wrong" and probably quite
expensive...
