If you're talking about Database Browser for SQLite (formally named SQLite 
Database Browser), at least at one time (version 3.5) it executed each query 
twice, apparently the first time to figure out the return types, and the second 
time to display the results (this caused me a certain amount of trouble until I 
realized the initialization function for my extension was being run twice by 
SELECT load_extension, and I fixed the function to be OK with being run 
multiple times). ?It wouldn't explain a 3x+ slowdown, but would explain a 2x 
anyway.

 I have noticed that SQLite Query Browser is running slower than other IDEs, 
including SQLitespeed, for some reason.? Even when each IDE is set to using 
similar versions of the SQLite3.dll.? We had a recursive query in SQB take 6 
min, on other IDEs it would be less than 2 min.
