I agree. I have installed a fresh new Solution Manager 7.1 from SAP media, patched it to SP14 with patch DVD and xml file that came with download basket. Now I´m running SOLMAN_SETUP....
Webdynpro called by SOLMAN_SETUP is very slow, and for my surprise, machine is not pushed at all. CPU remains low and I´ve got half physical memory free at my server. It is a x86 running windows 2012 with 24 Gb ram and a cpu with 4 cores.
Running sgen now to see if it gets better.
