It took me significantly longer. But, I’m also dealing with 30 columns — would that matter, even though I’m just using mmm3 for the wj?
In testing, when I make the data table that im searching (data;(max:`mmm3)) smaller, things speed up. For example, I ran a 1 minute xbar on that table and the windowjoin now takes a couple seconds.
I dont understand what I could be doing wrong. At full scale, 800,000x30cols, it took like 30-40 minutes to complete a 5 minute lookback.
