I'm running Google Chrome. When I do anything that'll save a file to my local filesystem - right-click and "Save As", click a download link, save an image - nothing happens for a good 20-30 seconds, and then suddenly the operation proceeds as normal.

The browser remains responsive whilst this is going on - I can navigate to other pages and so on - but the delay is infuriating. Especially since it often looks like nothing's happening, so I'll hit the download link again - and again - and then suddenly end up downloading four copies of the same file.

Any ideas?

similar happens to me when using a file upload element to select a file –  Andrew Bullock May 10 '12 at 11:31
    
I wonder if it is Chrome's "safe browsing technology" that is scanning the url and download? You might disable this feature temporarily to see if it makes a difference..superuser.com/questions/387724/… –  Moab May 10 '12 at 15:08

The same happens on my computer. I have the default download directory set up to save to an external USB hard drive.

The drive always has to spin up before the file is saved. You can hear and see this process very clearly.

20-30 seconds to spin up a drive? O_o –  grawity May 10 '12 at 13:09
    
@grawity: The drive goes into powersafe mode once it isn't used for a while. Once I access it, it has to completely power up again. It's quite annoying :P –  Oliver Salzburg May 10 '12 at 13:27

I know this isn't technically an 'answer' per se. However, it drives me nuts too! What I have found is that Chrome is checking for updates, which causes the delay.

Next time it happens, click the customise icon in the top right corner, click 'About Google Chrome' and just below your existing version, you will see it checking for updates. Once that process has finished, the downloads begin as normal.

It usually only happens to me once per 'session', but it's still infuriating and I don't know how to prevent it from occurring.

I would disagree here, I have the same issue, regardless of whether Chrome is updating not. –  Kev Jan 25 at 23:42
    
Not sure if coincidence or not, but it was updating for me at the same time. –  Bashar Abdullah Jul 17 at 12:20

Anything to do with the filesystem, I'd get a copy of Process Monitor.

Then see what's happening on the filesystem, Filtering on your path. See if Chrome is waiting or another process.

Do you face the same problem when you are using another browser such as Mozilla Firefox or Internet Explorer? If so, then the problem most likely has to do with Windows.

If you have recently install any new applications, use Windows' System Restore to rollback the changes.

Another common problem on Windows Vista or Windows 7 is when performance is much worse after installation of updates - that you may not be aware off. Usually this problem goes away after a few reboots.
