Indexing the content of files is nice when you have only a few dozen
files. When you have thousands and thousands of PDF files content
indexing is just a nightmare, a big cpu/memory/disk waste and does not
work at all. Baloo should be completely optional and never be
Oh, it works here on dual SSD BTRFS RAID 1:
% LANG=en balooctl status
Baloo File Indexer is running
Indexer state: Idle
Total files indexed: 395,505
Files waiting for content indexing: 0
Files failed to index: 0
Current size of index is 3.89 GiB
And it is very nice in combination with Alt-Space for invoking KRunner.
I added some exclude folders though to reduce the amount of files a bit – from '.config/baloofilerc'
exclude filters=[…],*.ytdl
exclude folders[$e]=$HOME/.cache/,$HOME/.local/,[… some backup and
archival folders…]
I reported *.ydtl for youtube-dl and AFAIR it has been added upstream as
a filter.
activated by default. Same thing for Akonadi. My only gripe with KDE
is it is full of "utilities" and "features" enabled by default that
produce more problems than benefits. One you disable / uninstall all
of them, KDE works like a charm.
Well actually I removed the executable permission from
akonadi_indexing_agent again. Cause here I indeed I'd say it does not
really work very well, at least not with lots of mail. Why?
Mostly cause it blocks out foreground activity like I click on a mail in
KMail and like to see its contents. But also cause the whole indexing
traffic goes through the database, be it MariaDB or PostgreSQL. Basically
I have seen the laptop at limits with I/O to SSDs for minutes and more.
Here I can confirm that it bogs down other workloads. When during an
Akonadi upgrade akonadi_indexing_agent is replaced with a new version
and thus is executable again, I usually notice it cause at some time
when the indexing kicks in the laptop becomes so slow, that I usually
kick the akonadi_indexing_agent process, but then also stop Akonadi,
cause the database would otherwise continue to do lots of I/O for
minutes.
Anyway to cut a long story short: The issues are known. Daniel Vrátil
was working on it ("make indexing great again") but while he completed
parts of the work there is still a piece missing.
Of course it is just my opinion.
Of course your mileage may vary, especially in case you have still files
on a hard disk.
