OSNews, Generic OSes No, your eyes aren't deceiving you - we have actually have not one, but two news items on hobby/small operating systems on the same day! You thought the day would never come again, but hey, here we are. You're welcome. Now, what are we talking about? FreeDOS - a test release has been, uh, released for FreeDOS 1.1.

Every system will have bottlenecks. It depends entirely on what is being done with it.

You could design a system without any bottlenecks but only if it only did one single thing, like operate a robot arm.

A robot arm realtime control system has no bottlenecks. The computer operates exactly as fast as the arm motors and sensors support.

A car's engine control computer or its anti-lock brake or dynamic stability control has no bottlenecks. It works just exactly as fast as it can.

But when you introduce a programmable system, the bottlenecks appear and change depending on what program is being run.

If you are downloading network files, a lot of CPU and RAM is being wasted while the network is the bottleneck.

If you're playing an arcade game, the RAM and network is going to waste while the CPU or GPU is at 100% use.

If you are processing giant databases in random access, the CPU is being wasted while the RAM or storage system is maxed out.
