How to make Power Query faster?
Performance depends on a lot of specific details. If there were optimizations that were universally true, then they would be built in. If your tables have infinite rows, then loading or transforming will take an infinite amount of time regardless of the rate involved.
Assuming you're asking about real-world (finite) load, to help determine if optimizations are possible, we'd need to know what data sources (e.g. CSV, folder, SQL server, SharePoint, etc.) you're working with and the approximate number of rows from each (just the order of magnitude is fine but infinite isn't a real answer). If they're all from a single SQL database, then you're much more likely to be able to make things faster than if you're trying to merge huge tables from separate sources.
Dude, it has about 500,000 rows. I pulled the data through a folder, where there were several CSV files and merged them to have only one table. This final table has more or less 500,000 rows.
