Guys my rig was lagging when run this miner
it's very hard work, not like other miner
maybe malware or something, tell me why
but miner running well just make my rig lagging for quadproc with 4 Gb RAM
The minerd is
not malware. It does nothing to your computer except use CPU time and a tiny bit of network bandwidth. You are choosing to run it, so you are allowing it to use your CPU - intensively! Your CPU will get hot as well because it is doing more and using electricity to do it. If you run the minerd on a laptop computer, it will probably get
too hot and slow down automatically to prevent overheating.
The minerd is a compute-intensive application. Mostly it sits there doing mathematical calculations (number-crunching). If the minerd process is run at normal process priority in Windows, you will definitely notice that it "gets in the way" of your other work on the computer and you get the impression of "lagging". The same thing would happen for example if you were encoding a video file to another format while using your computer for other things as well. Any compute-intensive application will show this effect.
If you want to use your computer for other things while running the minerd, it is best to start the minerd process with low process priority, or change it to low priority using the Task Manager. If you do this, you will hardly notice that the minerd is running at all
.... until you look at CPU utilization.
