I'm planning our upgrade to EPDM 2015.  After seeing these problems with the first two SP's, I'm hoping SP3.0 will be stable. I can't go thru another disastrous upgrade like 2011 Sp2 where we had CPU and memory issues which slowed server to a crawl.

Luckily I can do a test server upgrade, but that never really can show real world performance with all users working in EPDM.
