Your problem
My problem is: mautic CSV data importing is very slow
We have a CSV file with around 100,000 records that we’re trying to upload with a limit of 200. Unfortunately, the upload process is extremely slow, and the contacts are taking over 48 hours to upload completely.

Hi, this can be the result of:

  1. not enough resources (you have a 1GB MEM server with 1 CPU and pay only like $20 for it)
  2. you DB doesn’t have index on email address in the leads table
  3. you have WAY TOO MANY columns in your csv
  4. you had an error and it stopped
  5. your cronjobs are not set or set wrong
