Windows 8.1 has been fast on my iMac 5K Fusion drive. Even the boot time isn't so bad. Of course, SSDs are faster. Maybe something is not quite right with your installation? Try installing Bootcamp drivers again?

If you have a Fusion Drive, that's normal.

You might as well as get an external Thunderbolt SSD and run Windows off that drive.

Instructions to get it running in UEFI, TB or USB:

Connect external drive to Windows VM. You must have a Windows VM in VMware/Parallels.

What you need:
install.wim file (obtain this from your Windows ISO)

Open elevated cmd.exe

Note: All commands aren't case sensitive, including pathway to files.

Type diskpart
Type list disk
Take note of the disk you want to select
Type select disk 1 (if your disk is Disk 1)
Type clean
Type convert gpt
Type create partition EFI size=100
Type format quick fs=fat32 label=EFI
Type assign letter=S
Type create partition primary
Type format fs=ntfs quick label=W2G (or any other name you wish for label)
Type assign letter=E
Type exit

Open up File Explorer. In your C drive, create a new folder named WIN2GO.
Put the install.wim file in this folder

Back in cmd.exe:
Type dism /apply-image /imagefile:C:\WIN2GO\install.wim /index:1 /applydir:E:\ (this process will take quite a while)
Type E:\Windows\System32\bcdboot E:\Windows /s S: /f UEFI

Restart your entire Mac. After the chime, hold down Option and when prompted to select your boot drive, select EFI Boot.

Proceed installation normally.

After installation, install Boot Camp drivers.

the windows are fast just the boot time is not as fast as the OS X.

Make sure you select the start up disk in System Preferences or Boot Camp Control Panel. You do not want the computer to waste time looking for a start up volume. The reason that Windows is slower than OS X is that OS X installs to the SSD portion of the Fusion drive where as the Windows partition is only allowed to be installed to the spinning hard drive portion.

thanks, there is any way to make a short key of start up disc to the desktop or to the dock to not go through the preference menu for reboot?

Even TB1 is fast enough, or even a USB SSD.

Transcend makes pretty good ones.

With a 960GB JetDrive from Transcend (USB 3), my boot time is just 14 seconds into Windows.

can you post a link of this model?

Ask and you shall receive: http://www.amazon.com/Transcend-JetDrive-Upgrade-Macbook-display/dp/B00JKCHMP0

It's meant to be put in an Ivy Bridge Mac, but I left it in the USB enclosure that came with it and used it as an external SSD.

128GB of it is dedicated to Windows, another 128GB as an emergency bootable OS X partition and the rest of it is for storage and scratch space.

Reads are around 430 MB/s and writes are around 380-400 MB/s.

Depending on how much you can afford, TB is always preferable because you can enable TRIM over TB, but not over USB.

The LaCie enclosure works over both TB and USB.

and

http://www.amazon.com/LaCie-Rugged-...d=1420554871&sr=8-4&keywords=LaCie+Rugged+SSD

Whether or not TB is faster than USB 3, that depends on the interface controller itself.
