This is indicated by the glxinfo command, part of the mesa-utils package, which should return direct rendering: Yes when used: $ glxinfo | grep "direct rendering" The first step is to verify if direct rendering is actually enabled.

If applications using direct rendering are slow (i.e those which use the GPU, such as video players, games, or even a window manager), then improving GPU performance should help.

This can be monitored in several ways, for example with htop, pstree or any other system monitoring tool: $ htop

If CPU load is consistently high even with enough RAM available, then try to lower CPU usage by disabling running daemons and/or processes.

A value higher than 40MB/s (while idle) is however acceptable on an average system. Note: hdparm indicates only the pure read speed of a hard drive, and is not a valid benchmark. The speed of a hard drive can be measured with the hdparm command: # hdparm -t /dev/sd X If boot time is slow, and applications take a long time to load at first launch (only), then the hard drive is likely to blame.Use the following command, and check the "available" column: $ free -h If the computer becomes slow when large applications (such as LibreOffice and Firefox) run at the same time, check if the amount of RAM is sufficient.The system specifications can help identify them.

The best way to tune a system is to target bottlenecks, or subsystems which limit overall speed. See also Gaming#Improving performance for additional gaming and low latency specific advice. This article provides information on basic system diagnostics relating to performance as well as steps that may be taken to reduce resource consumption or to otherwise optimize the system with the end-goal being either perceived or documented improvements to a system's performance.
