I noticed the 15-20ms processing delay was happening on hits to the api.php page...

15-20ms delay until the page *starts* rendering, or *finishes* rendering?

 

[Catch-22]

Delay is probably the wrong word to use, what happens is that the relay request takes 15-20ms longer. I measured using a proxy on my local machine, hopefully this ASCII diagram makes sense.

              0ms                                                               300ms             
               |                     0ms                 280ms                    |               
               |                      |                    |                      |

I thought you meant 15-20ms *added* to something by kolmafia, as compared to vanilla kol in browser?
Or do you get answer from kol server in under 5ms if you hit api.php in vanilla kol?

EDIT:
actually, it's

browser
proxy .. 0ms
kolmafia
proxy .. 0ms
server
proxy .. 280ms
kolmafia
proxy .. 300ms
browser

so 20 ms pretty much on kolmafia
