Which is faster pandas or CSV?

Does pandas read CSV faster than Excel?

Importing csv files in Python is 100x faster than Excel files. We can now load these files in 0.63 seconds. That's nearly 10 times faster!

Is pandas as fast as C?

Pandas is certainly fast. I doubt if it's faster than pure C++, but as I'm sure you know the only way to tell for sure is to profile each solution. The best tip I know of for speeding up Pandas timeseries CSV parsing is this: Use a custom date-parsing function that utilizes string-slicing as opposed to strptime.

Is pandas faster than Modin?

Modin reads CSV files faster than Pandas for all file sizes except 5MB (the smallest file tested) The difference in performance is greater the larger the file size. Modin took a disproportionately long time to process the 5MB file: 0.23s, compared to 0.12s for the 10MB file and 0.16s for the 15MB file.

Why is Parquet faster than CSV?

Yikes. Parquet files take much less disk space than CSVs (column Size on Amazon S3) and are faster to scan (column Data Scanned). As a result, the identical dataset is 16 times cheaper to store in Parquet format! Once again — yikes!
