Thanks for letting me know!
How large is the file (number of row)?
The beta version of CSV Import is much faster at importing a large number. I tested a file with over 100K and left it run until it imported 20K. The current released version, each import step takes slightly longer than the step immediately preceding it because the CSV has to be parsed and then read on each step. In do so it has to re-read rows already imported in order to get to the rows not imported. The beta version parses the file a single time and then saves the parsed results to a bunch of individual machine readable files. So, on each step, the import only needs to pick the next file in the batch and import data within. On significantly large CSV files, the make massive improvements to the time require to import.
If you are interested in trying the beta, navigate to the Connections : Settings admin page and click the Beta Versions tab. Enable beta support for CSV Import and saved. Next navigate to the WordPress Updates admin page. Nothing to do here, this should simply force WP to check for updates. Now navigate to the Plugins admin page where the beta should be available for you to install.
Hope this helps!
