My Mautic version is: v3.3.4  
My PHP version is: 7.3.18  
My Database type and version is: mariadb:10.5.10-focal (docker)

I have this segment “foobar-diff” that generates 2004 contacts.  
Very simple filter:

It’s working but it’s very slow, consume a full cpu core for 10 minutes every time it runs (every 15mins)

The filter is defined as:  
Includes Segments “Foo” with 13170 contacts  
AND Excludes Segments “bar” with 11166 contacts

Maybe related to [Slow segment updates? Try this](https://forum.mautic.org/t/slow-segment-updates-try-this/21496)

There’s any other way to make this run faster? maybe using tags instead of segments?
