I have an HTPC and media server running Mint 17.1 which is incredibly slow. The hardware specs are:APU - AMD A8-5600k (4x 3.6GHz)MB - MSI FM2-A55M-P33RAM - 4GBm, 1333MhzHDD - Boot: WDC WD10EALX-089BA0 (1TB, 7200RPM); Other: 4X 3TB, 7200 RPM + 1x 1.5Tb, 7200 RPMIt used to run Win 7 and there were no issues with it, but after a HDD crash I decided to try out Mint.Since I installed Mint a few weeks ago, the computer feels like a very, very old computer. From a clean restart:Opening Chromium takes around 30 secondsOpening the file manager takes 10-15 secondsTaking an app like Kodi/XBMC from fullscreen to windowed can take anything from 20-60 secondsIf try to do something like have Amarok scan my music collection, the PC basically freezes. It keeps scanning, but it eventually gets so slow that it takes 5 minutes just to wake up from sleep.The mouse lags in Kodi/XBMCYoutube videos can stutter (unrelated to buffering)Things that do work well are:Video playback in Kodi. I can watch 1080p videos with no issue.Games. Although the system isn't particularly strong, it can play games as expected. CS:GO, D3 and Skyrim (on very low settings) all work.Often, when the computer appears to be completely frozen, SSH or workspaces would still run reasonably smoothly.Plex Media Server usually works well. However, if the PC starts getting very slow, the videos it sends out can stutter.I basically know nothing about Ubuntu/Linux (this HTPC is my first attempt).   How can I troubleshoot this?
