Subject Re: Virtual Router Configuration Time Linearly Increases in 4.7
Date Wed, 10 Aug 2016 13:07:56 GMT
Hi,

I did discover that PR while looking, but  it's not that one. Our
production system has that PR in it as well, yet we still see the issue
with the virtual routers. Perhaps I am mis-remembering and I need to open a
new bug report?
