KB10747 - Editor very slow generating a vector layer topology project.

Check to see if anti-virus software is running in the background on the computer. The topology checking/building operation creates a number of special files to which data is repeatedly written during the course of the operation. If anti-virus software is checking each write-to-file operation, this can slow down the speed of the topology building operation by a factor of 10 times or more.

Try temporarily disabling the anti-virus software while the Editor is building the topology.
