Does ram improve my startup time software#
If you have multiple disks available, you can set them up as a software RAID for serious speed improvements.Ĭreating swap on a separate disk can also help quite a bit, especially if your machine swaps frequently. Make sure that your partitions are properly aligned. USB Device Tree $ lsusb -t PCI Device Tree $ lspci -tv Partitioning The following commands will help you determine the various paths on your machine. This is because most of the time the front and back ports are internally connected to separate Root USB Hubs, meaning you can send more data at the same time using both instead of one. This can be avoided because motherboards usually have several "pipes".Ī concrete example of this would be if you have two USB ports on the front of your machine, four USB ports on the back, and four disks: it will usually be faster to connect two disks on front and two on back rather than three on back and one on front. The reason is that each "entry path" into the motherboard is "like a pipe", and there is a set limit to how much can go through that pipe at any one time. By spreading your storage devices across multiple connection points you can avoid bottlenecks. There are different ways to connect through the motherboard such as the NIC, PCIe, Firewire, Raid Card, USB, etc. They can however be measured by benchmarking tools.Īn internal hardware path describes how the storage device is connected through your motherboard. The effects of optimization are often difficult to judge.
However, the default kernel can be tweaked as shown in certain parts of this article to perform better. Using an optimized kernel improves performance.Use a more lightweight environment or create a custom environment if the current does not meet the hardware and/or personal requirements. When running a desktop environment, disabling (unused) visual desktop effects may reduce GPU usage.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.
