LoL, just had my dinner and was googling about why kernel can't be updated without rebooting and accidentally came to this site, and to my surprise the name of the site is "kerneltrap", but its trapping ppl like me (Laughs). So time to search the topic again.

A bottleneck is quite literally a small part of your installation (hardware or software), where too much processing is being funneled through a specific area. In other words, far too much is going on in one particular area of an installation, in comparison with any other part.
