I didn't put it on the forum because it occurs with a perfectly stock brand new install of 0.20+0.20.1 only, it seemed to me to be more of a bug than anything.

I would recommend that you give it a try on the Forums nevertheless, there may be a workaround.
Anyway, thanks for the logs, this way we can see if there is any correlation between the systems experiencing these issues.

I can confirm that this is definitely not an isolated incident; my own computer is also having this issue with 0.20 (sound files take a very long time to load) and 0.20.1 (sound files and all .png and .jpg images take a very long time to load).

Most relevant system specs:
AMD Phenom II X4 965 Processor
16GB Corsair Vengeance DDR3 RAM
Windows 7 Home Premium 64-Bit

EDIT: I notice that both my processor and the original submitter's processor are from the exact same line. That may be the most relevant link at this point.

The issue seems to be not specific to a processor.

Here's the DxDiag from my own system: http://www.skyrender.net/DxDiag.txt
And the DxDiag from a third user having this issue: http://pastebin.com/zR269DSi

After some additional testing, we have deduced that the likely cause is a switch to file:// loading methods. Details can be found here: http://forum.kerbalspaceprogram.com/showthread.php/29176

A potential fix for this has just been mentioned in the forum thread for this. It works for myself and a few others.

The game takes very long to load and it doesn't get any faster when loading from an SSD instead of a HDD, tells me it's not storage limited, it's doing something during load that slows it down beyond what loading all game assets from drive into RAM would require.
