Importing Contacts is taking a very long time!

Hello! I’ve followed the instructions below but am still finding that my Mautic installation takes a VERY LONG time to upload a list of contacts: https://www.devside.net/wamp-server/apache-and-php-limits-and-timeouts

Have you guys found anything else that’s helpful to speed up the import process?

Hi,
questions:

  • are we talking about 1 million or 10.000 ?
  • are you using batch import (background) or browser?
    Thx

The list is around 45,000.
We are using browser.

Thank you for the help!

Strongly recommend you using the Cron-based background import rather than browser based with those numbers!

Also as a side note, we use gender inclusive language in this community, please use ‘folks’ or alternatives rather than ‘guys’ :slight_smile:

Thank you for the suggestion! Where could I get some more information and directions about using Cron-based background import?

Just a comment to the import topic.

I hear it over and over again, that import is too slow.
Import is not fast anywhere else either. It takes lots of resources to import/merge/verify data.
I think it makes sense to make it even slower (and safer) with cron jobs by using the following settings:
If you run the import cron every 5 min, can use:
mautic:import --limit=2500

If your freshly imported data will trigger segments to update, you should limit that as well:
mautic:segment:update --batch-limit=2000

If your 45.000 contacts start receiving emails, you might want to set your cron accordingly:
mautic:emails:send --message-limit=2000

Will it send “slow”? Yes. Buit it will be stable.

Good luck
PS: slow sending is good for inboxing
