Azure & unexpected WaIISHost.exe CPU usage

Hi All, I am uploading the project to azure according to the wizard.

As soon I start upload files to azure blob at the final wizard step, I am starting to get the sawtooth CPU usage. You can find screen shots here and there.  Thus, even without any site visitors, I have not too small, for about 30-40%, CPU usage under windows Azure (2 small web role instances according the wizard. Mojo search disabled, mojo log switched to SQL).

Could we expect some improvements with azure usage or maybe I've done something wrong?

Warm regards, btw, thanks a lot for artisteer plugin!!

Igor

sorry, some additional info: when mojo upload to the azure blob finished, the CPU usage _remains_ high. That is seems to be the problem.

Regards.

Hi Igor,

When you upload to blob storage I would expect the processor to be working hard for a while while the files are synced to the web roles.

However a lot of changes ahve been going on with Azure and I'm not sure this synchronization technique is the best solution given some of the new possibilities. From Scott Gu's post it sounds like it is now possible to share a data drive accross web nodes and this might be a better way to map the /Data folder where user uploaded files are stored, and the rest of the files can be part of the web role image.

I plan to investigate these things when I get some time but I'm not sure how soon that will be.

Best,

Joe

Hi Joe, thanks a lot for your comment. Yes, as far as I could see, there is a fast  microsoft's movement with azure right now, I will try to take a look into  "sites" solution in compare with current solution. Sorry, i have no link in english.  Again, thanks a lot for your efforts!!

Warm regards, Igor
