I too have noticed recent versions of koha are very slow on the
bulkmarcimport.
Both dev and package install. Both new installs (3.18.02.000).
The larger system (16Gb) took about 10 hours bulkmarcimport for about
400,000 records being about 667 per minute.
The smaller is progressing at a similar rate.
I did notice that the zebraqueue table was building up as the load
progressed whereas previously I was sure I had to perform a
rebuild_zebra afterwards.
I wonder if additional processing has been added to bulkmarcimport which
might benefit smaller loads by flagging for zebra updates, but has a
major impact on larger imports.
If so, would it be better to have a command-line switch to avoid the
extra overheads?
I hope this helps the discussion.
All the best.

I'm finding a quite slow import into a Koha DB with bulkmarcimport.pl.
It imports only 800 record in 1 minute.
With top:
90-95 % bulkmarcimport.pl
5 % mysql
apache, zebra, indexing are down.
Down the list rather than down=not-running, I hope!
no MJ Ray, down=not-running.
I imported 300.000 biblio records in a empty Koha.
At the end the speed is 1200 record in 1 minute as average.
Records without items are much more fast.
I'm trying to understand better the situation.
