A couple things - Lag and Slowness are a bit general - are you having the same lag hovering over icons?You're using LL3.0 Ubuntu base is 16.04; 14.04 fixes may or may not resolve exactly... For the hardware you shouldn't notice any slowness in general... If the slowness is similar to the icons as with the link provided - it maybe graphics related (updating driver) but I'm going to take a stab and say the slowness you're experiencing is related to internet browsing/connectivity??? Again this is my guess as I see its a Broadcom I'm curious to what's slow for you.. Pinpointing exactly will yield different drivers to update/support. Also before updating drivers; I would suggest making a Systemback backup, if updating drivers have an ill effect it will be easy to revert back. Some info on Broadcom - https://www.linuxliteos.com/forums/network/(solved)-broadcom-wireless-issue/msg4997/#msg4997 But searching will result a lot of results.. Again if the slowness is network related I was posting the same time as Jerry... Or as he suggests....
It's O.K, but 5 to 6X slower than an SSD
You can also do a quick test on the disk:Use whatever your sdx is, a, b, c For comparison,On a good WD Hard DiskCode: [Select]sudo hdparm -t /dev/sdb/dev/sdb: Timing buffered disk reads: 332 MB in 3.00 seconds = 110.57 MB/secOn Samsung SSDCode: [Select]sudo hdparm -t /dev/sda/dev/sda: Timing buffered disk reads: 1494 MB in 3.00 seconds = 497.68 MB/sec
sudo hdparm -t /dev/sdb
sudo hdparm -t /dev/sda
Just my plugged nickle and to maybe add help to then00b.... Defragging was the go to for Windows for PC slowness, usually; clear temps, cache, disk clean up and defrag... You can also use "Lite Tweaks" to clean up/maintain the system similarly to disk clean up.. Anything marked safe is a no brainer; those marked caution are more so for specific fixes for problems so be mindful when selecting.For slowness, maybe adding a bit more info; when are you noticing the slow down.. browsing, working with "XX" application or in general = boot up etc.. Along with system specs or the output of Code: [Select]inxi -F
inxi -F
