Size limits on MLO & performance?

[Jon R]

Hi, Does anyone have experience of large numbers of tasks/projects etc, and MLO slowing down or crashing/corrupting as a result?

Or put another way do users/devs have any tips on how to structure MLO file(s) to optimise performance? e.g. what is the largest comfortable number of items?

Using a newish win10 PC with Intel i7 and 8GB ram, SSD.

Reason for asking, I have a single MLO file 'all in one' to get a grip on life(!) but my perception is it is starting to struggle with ~3k items.

Ideally I would like to keep adding items (instead of spawning 'child' project files). But starting to think that isn't realistic.

Thanks in advance!

I have over 11k tasks and have no issue on the desktop version.  The app I get the annoying message about having too many tasks but haven't seen that it is causing any problem.  I don't use the mobile app a lot though.

I have had issues a long time ago with crashing but it was caused by something else and support helped me get it fixed.  I believe it took a reinstall but I may have had to go back a version.  Right now I am up to date with the current version and working without issue with over 11,000 tasks.  I use it all day everyday.

I'm the ultimate hoarder. I don't delete or archive anything, and I've
been using MLO for about 10 years.

I have two major MLO files: one for home and one for work. According to
Properties...

Home = 11,773 Total to-do items
Work = 27,843 Total to-do items

I have megabytes of notes in each file: 7.3 MB in Home and 9.3 MB in Work.

Effectively I (mis-)use MLO as a repository for everything I've ever
done, in case I have to do it again.

On my PC both files open within a second or two and are lightning fast
to do anything I've needed. My hardware is about the same as yours (16
GB RAM and a lesser processor; MLO files on non-SSD media or an
encrypted USB stick).

I'm pretty sure that over many years the only crashes have been caused
by other apps or the OS, and I don't think I've lost so much as a single
byte of data that I've been adding. Keeping copious MLO backups
configured in the options has helped. I cannot think of another app that
has been so rock steady and reliable.

I sync my home MLO file with Android, and there it's not so clear cut.
To open the file and get to the "All Tasks" view for searching through
everything takes about 30 seconds. That might be unacceptable for some,
but I only use the phone to add new items to Inbox (takes no time at
all) or look up something from my years of collected cruft. For me, the
30-second trade off is worth it. Searching/filtering, once all tasks are
loaded, takes less time than the typing.
