Same problem on AmigaOS I think, although as I'm using a proper HDD
the delay is negligible (and the disk cache makes a noticeable
difference).

Remember that write speeds on SD cards are significantly slower than
read speeds, and lots of small writes are slower still.
It would be interesting to see if a Raspberry Pi running the GTK
version from SD card has the same slowness.
