Delete rows takes forever

[GWC]

a1.a188000 contain values.

I type =if(a2=a1,"dupl","") in b2
I copy that formula and paste it in B2.B188000
I select col b
I do FIND ALL dupl
It finds 12000 cells.
I press the Shift key and click on the first and last cells in the box
I do DELETE rows

Why does it take HOURS to delete the 12,000 rows?

I did what you suggested and it's taking 30 minutes and counting.

then go another way:
Write in B2
=IF(COUNTIF($A$2:$A$188000,A2)>1,"Duplicate","")
and copy down.
Then filter column B for "Duplicate" and delete contents of all visible
cells. Select column A and sort to eliminate the blank cells.

if you use xl2007 or later you can also try it via Data => Remove
duplicates.
Or (with all versions) you can filter with advanced filter without
duplicates to another column.
