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 algo

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)
