Yes, there are triggers. I didn't post them because I didn't see any 
correlation to the DELETE query as they are only INSERT and UPDATE triggers:

CREATE TRIGGER item_inserted AFTER INSERT ON item BEGIN UPDATE trace SET typeid 
= (SELECT id FROM "type" WHERE name = 'modified') WHERE trace.id = new.traceid; 
END
CREATE TRIGGER item_modified AFTER UPDATE OF traceid, freq, value, noiseflag ON 
item BEGIN UPDATE trace SET typeid = (SELECT id FROM "type" WHERE name = 
'modified') WHERE trace.id IN (old.traceid, new.traceid); END
CREATE TRIGGER meta_global_insert INSTEAD OF INSERT ON meta_global FOR EACH ROW 
BEGIN INSERT INTO metadata (parameter, value) VALUES (NEW.parameter, 
NEW.value); END
CREATE TRIGGER meta_global_update INSTEAD OF UPDATE OF parameter, value ON 
meta_global BEGIN UPDATE metadata SET parameter=NEW.parameter, value=NEW.value 
WHERE id=OLD.id AND datasetid IS NULL; END
CREATE TRIGGER meta_dataset_insert INSTEAD OF INSERT ON meta_dataset FOR EACH 
ROW WHEN NEW.datasetid IS NOT NULL BEGIN INSERT INTO metadata (parameter, 
value, datasetid) VALUES (NEW.parameter, NEW.value, NEW.datasetid); END
CREATE TRIGGER meta_dataset_update INSTEAD OF UPDATE OF datasetid, parameter, 
value ON meta_dataset WHEN NEW.datasetid IS NOT NULL BEGIN UPDATE metadata SET 
datasetid=NEW.datasetid, parameter=NEW.parameter, value=NEW.value WHERE 
id=OLD.id AND traceid IS NULL; END
CREATE TRIGGER meta_trace_insert INSTEAD OF INSERT ON meta_trace FOR EACH ROW 
WHEN NEW.traceid IS NOT NULL BEGIN INSERT INTO metadata (parameter, value, 
datasetid, traceid) SELECT NEW.parameter, NEW.value, datasetid, NEW.traceid 
FROM trace WHERE id=NEW.traceid; END
CREATE TRIGGER meta_trace_update INSTEAD OF UPDATE OF traceid, parameter, value 
ON meta_trace WHEN NEW.traceid IS NOT NULL BEGIN UPDATE metadata SET 
datasetid=(SELECT datasetid FROM trace WHERE id=NEW.traceid), 
traceid=NEW.traceid, parameter=NEW.parameter, value=NEW.value WHERE id=OLD.id 
AND itemid IS NULL; END
CREATE TRIGGER meta_item_insert INSTEAD OF INSERT ON meta_item FOR EACH ROW 
WHEN NEW.itemid IS NOT NULL BEGIN INSERT INTO metadata (parameter, value, 
datasetid, traceid, traceid) SELECT NEW.parameter, NEW.value, t.datasetid, 
t.id, NEW.itemid FROM itemid i LEFT JOIN trace t ON i.traceid=t.id WHERE 
id=NEW.itemid; END
CREATE TRIGGER meta_item_update INSTEAD OF UPDATE OF itemid, parameter, value 
ON meta_item WHEN NEW.itemid IS NOT NULL BEGIN UPDATE metadata SET 
datasetid=(SELECT t.datasetid FROM item i LEFT JOIN trace t ON i.traceid=t.id 
WHERE t.id=NEW.itemid), traceid=(SELECT traceid FROM item WHERE id=NEW.itemid), 
itemid=NEW.itemid, parameter=NEW.parameter, value=NEW.value WHERE id=OLD.id; END

Looks like you have triggers going on there. You only gave us the table and 
index definitions. What are the on delete triggers you have?

Sorry to disappoint you, Keith and Simon, but in all cases the database file 
has been located on a ramdisk. It's only about 50 MB in size, btw.

Yes and no. Of curse, I had MariaDB run on the same machine, and its data files 
had been stored on the same ramdisk.

I did it again, same file:

SQLite version 3.30.1 2019-10-10 20:19:45
Enter ".help" for usage hints.
sqlite> pragma foreign_keys=on;
sqlite> .timer on

> You haven't shown the "explain query plan" Keith asked for

Is the beginning of it enough or do I have to repeat the entire DELETE? Here is 
the output which I canceled after some seconds:
