In the first minute after the page loads, the app receives the instrument lists of some sixty exchanges. Each list used to be handed over as one block and copied whole, and the biggest of them held the page for two to four seconds: the frame counter kept going, but the pointer stuck, the crosshair stopped and clicks landed late. That was the stutter several of you described.

The lists are now converted a few milliseconds at a time, between frames, and the app keeps only the fields it uses instead of every venue's raw record. Warm-up takes the same wall-clock time, but no single frame waits for it.

The browser console is also quiet by default now; the remaining diagnostic lines appear only when debugging is switched on.
