You can control the number of records imported at once by adjusting the chunk size setting. This allows you to import between 10 and 100 records at a time. We recommend using a lower chunk size for shared hosting environments, but on robust cloud-based hosting, you can set it to 100. The feature for adding custom taxonomies will be available in the next release.
How many posts can it import at once? Is there a limitation on the size/volume of records? Also, is it able to populate custom taxonomies?
