Mautic CSV data importing very slow

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
    Here is an article to help you out:
