Bootcamp (Win7) slow after Yosemite upgrade

Since you are switching between the two OSes by power-cycling the machines, they cannot impact each other. You should address W7 issues as separate isolated issues.

Is this a single-disk iMac or does it have a Fusion drive?

If you have an HDD which is fragmented, it can slow your machine down, irrespective of the OS you have running. OSX pins as much as possible in memory, so there may not be a perceptible change. Windows paging may be causing issues which are coincidental with the Yosemite upgrade. Either de-fragment the disk on both OSX and Windows side, or backup both installations, and erase disk and restore both from a backup. There are some challenges with restoring a Windows backup to a BC partition, but there are third-party commercial products which can address some of these. Another option on older Mac hardware is to replace HDDs with SSDs/SSHDs.

Is it possible either the drivers I downloaded to usb via Bootcamp assistant in Mavericks for Windows 7 no longer function properly? I can only run Bootcamp 4.0. I was mistaken about my iMac, it's a mid-2009, not 2010.

From Boot Camp Support Software 4.0.4033 supports iMac (20-inch, Early 2009 & Mid 2009). Once BC drivers are installed, the only methods of a driver update are via Windows Update or manually via BC or downloading drivers manually from a non-Apple website. If you have Windows Update enabled, you can check driver versions by looking at (example from Windows 8.1).

Since the upgrade, I'm also unable to get into Bootcamp via holding down option when I startup the machine. The icons don't show up. I have to do it via system prefs > startup disk. That doesn't seem right.

The Yosemite Bootmanager has some differences with Mavericks, but this should work. Was you Windows partition resized at any point in time after the original Windows installation?

After Yosemite upgrade my Macbook Pro Retina does wait about 30seconds to one minute before booting Windows7-64. This behaviour is really annoying.

If you turn off WiFI (in Windows) and disconnect all external peripherals, do you see any improvement in boot speeds. Do you have a Fusion drive?

Macbook Pro Retina Win7-64Pro.

It has one local Drive Apple SSD SM256E ATA Drive. I deactivated BT, and Wireless in the device manager.
I still have a very long black screen before Window does start on this machine, restart is normal.

So when I turn on the Macbook, I got a black screen for about 30secs - after that I do see the normal windows boot logo.
When I start OSX it`s about the same time where I see a progress bar due to Yosemite startup, ....

no external peripherals are connected to this machine.

What year/model is Mac? It seems the CSM-BIOS layer which supports legacy BIOS installation is slow on your Mac.

NTFS-3g conflicts with the Apple NTFS driver. It can slow down the switch during reboot. Can you disable NTFS-3g for your BC volume and test.

I removed all non Apple NTFS Utilities from OSX. BC still features a very long delay before booting w7. Restart is quick tho.

Do you have the fuse_wait patch also installed? You should remove it too. Also, the CSM-BIOS layer invocation is slower than EFI boot the first time. Restart of Windows does not require this to happen again, since it is already loaded.
