Performance enchancement

[newptcai]

I have a complicated section on my daily journal which tracks what I have done and should do each day. It gets painfully slow on my laptop. When I edit it, I see a significant jump in CPU use.

Is there any way to speed this up a bit? I have trimmed the number of tasks I have. But it doesn't seem to help.

## Todo || (+PENDING due.before:2023-03-23) or (+COMPLETED end.after:2023-03-22 end.before:2023-03-23) or (+SCHEDULED -COMPLETED schedule.before:2023-03-23) || due:today

### Work | @work | +work

### Personal | @personal | +personal

### Relax | @relax | +relax

### Computer | @computer | +computer

Other than trying the development version of taskwarrior which (I believe) uses a different storage engine, I don't think taskwiki can be sped up much. :-(

Now taskwarrior has updated to version 3.0, with the storage rewritten, maybe we can port taskwiki to use it?

Taskwiki uses whatever version of TaskWarrior is present on the computer (via tasklib). @newptcai have you seen performance benefit with 3.0 or newer?

I still use the old version taskwarrior because I synchronize across devices with Git. That's not very piratical if the tasks are stored in sqlite.

I have tried the latest version of Taskwarrior (3.1). It does not really speed up things.

I realized the main issue is that I have four different search criteria in one file. This perhaps means calling Taskwarrior four times. This definitely slows things down.

I wonder if taskwiki can speed up a bit by multi-threading?
