I suspect you're right - those details were for the day before I added
the request timeout. Rerunning it for yesterday gives:

api download    3d 15h 17m 35.710s   (51.3%)
potlatch        2d 19h 12m 34.401s   (39.5%)
api upload      12h 35m 59.514s      (7.4%)
other           2h 59m 06.956s       (1.8%)

Which suggests that a lot of Potlatch time before was attributed to a 
number of very long running (often many hours) attempts to fetch data 
for large areas. Those requests are now timing out after 5 minutes 
instead of running on for hours and hours.
