@Massimo I can assure you - not only Italians do think that way. "Do not touch a running system" is different than "Do not run a touchy system". The latter was the case here and could have been fixed by patching.

On UL you can keep track. SF has just too many questions per day, so I would rather vote for creating a Windows-Server branch to diversify SF further.

@voretaq7 I had an uneasy feeling about this question right when I asked it - it is in a very grey area - I knew that, but the question and answers should help professional sysadmins - and that is right on focus, is it not?

There were two reasons to ask this question. First - I came across that our Windows-Hyper-V-guys developed quite the same limits as we did with Linux/XEN. Second there was a question on how to reduce interrupts in a VM where the network-interrupts maxed out on a specific interface. IMHO this would max out on any VM-technique (if you stay with the same hardware).

Thanks for the edit and re-open. The answers up until now go into the right direction.

Good example. So basically you think sysadmins and software programmers are in a comparable position. This is a great relief - although it seems to make it a common IT-problem.

The statistics seem to say that my assumption is wrong here. So let`s get back to "off topic" - since tightening the "on topic" is out of question for at least three moderators here - I take your answer as "You may flag questions with non-professional background, that fit into other sites as off-topic and name the site it should be moved to. The moderators will be happy to do so (even for closed questions)." right?

@DJPon3 Citation? This is selv-experience. Perhaps my questions are too complex (one of this was not even my question)? This seems to be a common behaviour on every site - first scan the bounty-questions - then go for the rest. So a bounty question gets more attention (which is intended) but on SF I have the feeling that there is not enough attention for non-bounty-questions.

@Zoredache the blog article targets question-writers. Not people like me who mainly answer questions. I really like to answer more of them - lack of knowledge is not my problem here. It is lack of time to find these questions.

Currently I will not mark these off topic, since they are on topic (e.g. on SF AND UL).

Understand me right - SF is great. But currently the only way to get a proper answer is to set a bounty to a question. I do not think that this is normal.
