COSservice.exe processor usage

Is there a minimum cpu requirement for CBU? I am having some problems backing up a 134mb folder using cbu online storage. I have a good range of comodo products on this system and looking to test out cbu and cloud with the intention of using it for my small business use. Currently using, granted its a pretty old machine I’m using to test with just 1gig or ram and 1.9ghz cpu. The COSservice.exe is using 100 percent of the cpu causing the machine to lock up. Smaller files have uploaded ok but this one will just not go with error messages saying it couldn’t upload. The gui is also very slow, I have to set it off and wait 2/3mins for it to get going just to return the error message.

Also have problems getting logged out of CCloud but I guess that’s for another part of the board!
