Discussion installing to virtual box- why is net4.5 so slow ?

jb skaggs

I'm installing gm 2.0 to a win virtual ox on ubuntu 17.1 and when gm gets to net4.5 it takes almost an hour to get 99% done then it got to optimizing the build and after an hour hung, my whole ubuntu hung and I had to perform a hard reboot.

Any suggestions as to why? Or is there a history of this?
