Such circumstances can result in an elevated load average, which does not reflect an actual increase in CPU use (but still gives an idea on how long users have to wait)." 除了统计runnable和executing状态的process,还有处于uninterruptible sleep状态的process也会被计算,这个状态与IO相关。考虑到这个...

The kernel parses parameters from the kernel command line up to “–”; if it doesn’t recognize a parameter and it doesn’t contain a ‘.’, the parameter gets passed to init: parameters with ‘=’ go into init’s environment, others are passed as command line arguments to init. Ever...
This parameter allows you to specify a "message of the day" to display to clients on each connect. This usually contains site information and any legal notices. The default is no motd file. This can be overridden by the --dparam=motdfile=FILE command-line option when starting the daemon....
Find Top Processes By RAM and CPU Usage Brief explanation of above options used in above command. The-o(or–format) option ofpsallows you to specify the output format. A favorite of mine is to show the processes’PIDs(pid),PPIDs(pid), the name of the executable file associated with the...

How to Run A Command with a Given Nice Value in Linux Here, we will look at how to prioritize theCPU usage of a programor command. If you have a very CPU-intensive program or task, but you also understand that it might take a long time to complete, you can set it a high or fav...
having too little entropy during and after boot for generating crypto keys. This plugin mixes random values into the latent_entropy global variable in functions marked by the __latent_entropy attribute. The value of this global variable is added to the kernel entropy pool to increase the entropy...
(Note that the amount of I/O stays the same; only the time it takes to complete will increase if the files are fragmented.) You can use command LANG=C LC_ALL=C sed -ne 's|^[^"]* open("\(.*\)", O[^"]*$|\1|p' trace.* \ | LANG=C LC_ALL=C sed -ne 's|^[^"]*...
