I've recently started using Zorin 16.2 Lite on my personal (and obsolete) laptop, an HP Pavilion dv6748us. It's quite old (3gb od 667MHz DDR2 ram, Turion64 x2 Processor, and an Nvidia nForce 630M), but it's enough.
One thing that bothers me (but i know there is not much to do), are boot times. When I first installed Zorin, the first boot (as expected) took quite some time. But after setting up all my programs and fiddling with the nvidia 304.137 driver, boot times got down to 1:30 minutes (systemd-analyze time). I looked a bit on what could be stripped down to get better boot times, and ended up uninstalling flatpak and snap and disabled systemd-networkd.service. That took 40 seconds off the boot time. The thing that the first time I used systemd-analyze blame, man-db.service and udisks2.service, each one reported from 30 to 40 seconds (of what i think is "time to set up"). What is weirder, is that that only happens when I turn on the notebook after some time of being turned off, those services always take that time, but if I reboot, they take less than a half of that time.
Zorin is the only OS this notebook has installed, and the bios has no options about "fast boot", so, i dont know why that happens.
In any case, I will probably end up installing an SSD, but for the time, I want to try and reduce boot times as much as possible.
Here is some info about my system and current boot times:
