It varies depending on what you are doing, but is probably 100x faster on average.

Some things are literally 10000x faster because we are internally using algorithms with better asymptotic complexity than Excel, but there are a few edge cases where we are maybe only 10x faster

(but we are always working to improve that — half my job is just analyzing flame graphs and grinding out perf improvements)

When we claim 100x faster than desktop Excel, we're looking at supported row counts, import speeds from Snowflake, and time to drag large XLOOKUPs. We'll do a deep dive on performance in another blog post next week. Stay tuned!
