How big is the hard disk performance loss in a WUBI install of Ubuntu compared to a real dual-boot?

I am currently dual-booting Windows 7 and Ubuntu using WUBI. I have understood that disk performance under Ubuntu is ‘slightly slower’ when using WUBI compared to a ‘real’ dual-boot, but exactly how big is the performance loss?

Is it worth doing a real install and spend some time to figure out how to set up a dual-boot that allows me to have a separate data partition?

My hard disk has a read speed of ~83 MB/s according to my Ubuntu LiveCD. The rest of my system is relatively fast.

    Performance related to hard-disk access is also slightly slower, more so if the disk image file is fragmented, on a Wubi install compared to a normal one.

      Thanks for the link about performance, I'll consider it when I decide wether to do a real install or not.
      Also I'll try to defrag my current WUBI install to see if it helps.
