time (Unix) - can be used to determine the run time of a program, separately counting user time vs. system time, and CPU time vs. clock time. [1] timem (Unix) - can be used to determine the wall-clock time, CPU time, and CPU utilization similar to time (Unix) but supports numerous extensions.
Prints or sets the system date and time dirname: Strips non-directory suffix from file name du: Shows disk usage on file systems echo: Displays a specified line of text env: Displays and modifies environment variables: expr: Evaluates expressions factor: Factors numbers: false: Does nothing, but exits unsuccessfully groups
zram, formerly called compcache, is a Linux kernel module for creating a compressed block device in RAM, i.e. a RAM disk with on-the-fly disk compression. The block device created with zram can then be used for swap or as general-purpose RAM disk.
In contrast to the previous O(1) scheduler used in older Linux 2.6 kernels, which maintained and switched run queues of active and expired tasks, the CFS scheduler implementation is based on per-CPU run queues, whose nodes are time-ordered schedulable entities that are kept sorted by red–black trees. The CFS does away with the old notion of ...
The Linux Trace Toolkit (LTT) is a set of tools that is designed to log program execution details from a patched Linux kernel and then perform various analyses on them, using console-based and graphical tools. LTT has been mostly superseded by its successor LTTng (Linux Trace Toolkit Next Generation).
Tracking work hours with a browser plug-in is similar to time tracking software—and some have a plug-in available already. This method of tracking employees' hours works best for employees who ...
This means user applications iterating over and opening files in a large directory would thus generate many more disk seeks between non-adjacent files—a notable performance drain in other file systems with hash-ordered directories such as ReiserFS, [80] ext3 (with Htree-indexes enabled [81]) and ext4, all of which have TEA-hashed filenames.
Here are four strategies that project managers can use to get their teams on board with time tracking and get usable time data. 4 Ways to Make Tracking Your Work Time Less Miserable Skip to main ...
