Yosemite, Parallels, Win7 - terrible brakes. Just me?

Question

Virtualization

iMac 2011. Before the OS update (there was a Lion), everything worked fine, the parallel started quickly, Win7 loaded for a maximum of a minute and did not get stupid. Recently I had to upgrade to Yosemite 10.10.1, updated Parallels to 10.1.1, installed fresh win7 sp1 64x original. Terrible brakes - win7 starts up in 3-4 minutes, shuts down even longer, and it's a fresh OS without programs...
UPDATE: solution kb.parallels.com/122767

Answer 1

MacBook Air, Yosemite, Parallels 9.0, Win7 x86
1GB of RAM is allocated for Windows. No brakes. Although Windows is not particularly loading, maximum VS

Answer 2

So what do people usually do? That's right - publish logs. Makovsky (from console, stripped by 'parallels') and Windows. More precisely, they do not publish them, because at the time of publication they understand what exactly is broken. You, however, propose to strain your telepathic abilities - "why, on an incomprehensible configuration, it is not clear that it is not clear how it works. Ah, it's not entirely clear - SLOWLY!"
Well, I won't hint at the fact that Parallels has support, it's empty. It's easier to suffer.
