That's strange indeed. I wonder whether something is wrong with your setup --
 CI commands have never been pokey here. On the contrary, they're
instantaneous (except in very large files, in which case they're extremely
fast). In other words, no difference from Xy3.

The first thing I'd do is force the display into eXPanded view (func XP)
before executing CI. Xy4 is optimized for speed in eXPanded view (unlike
XyWin, which runs faster in graphics view).

Next I'd change every instance of BC to BX and every corresponding XC to Q2.
Blind execution of commands works a dramatic speed increase in most programs.

Finally, if you haven't already done so, turn on Error Suppression at the
beginning of your routine: BX es 1Q2.

If this doesn't do it, some deeper diagnostic digging will be in order. Let
us know.
