**Your software**  
My Mautic version is: 7.1.1  
My PHP version is: 8.3.30  
My Database type and version is: mariadb: 10.11.16

**Your problem**  
My problem is:

Hello Mautic community,

I am currently working with a project based on Mautic Open Source 7.x, running in Docker with the following environment:

- Mautic 7.x
- MariaDB 10.11
- Mautic container: `mautic/mautic:latest`
- Background imports executed with:

```auto
php bin/console mautic:import --no-interaction

```

For testing, I divided the contacts into three CSV files containing 23,400 rows each and configured:

```auto
'parallel_import_limit' => 4,

```

I then started three import processes simultaneously. All contacts were new and the database was clean.

These were the results:

```auto
Import 1:
23,400 contacts created
Time: 795.21 seconds

Import 2:
23,400 contacts created
Time: 793.56 seconds

Import 3:
23,400 contacts created
Time: 790.44 seconds

```

The actual total elapsed time was approximately 13 minutes and 24 seconds for 70,200 contacts.

Can I improve this time?  
Is there another solution that allows for faster importing?
