I've progressed from 16.04 to 20.04 & I'm happy except boot & app load times have increased with each upgrade. My SW is fully up to date. I have questions:

  1. Would a fresh install of 20.04 improve times?
  2. Would a change from my HDD to an SSD & fresh install improve times? My HDD is a Seagate Barracuda (ST320DM000-1BD14C) with an average seek time of 11ms. The SDD would be a Crucial BX500 with a seek time is 0.1ms. Thanks in advance, Trevor.

  • Generally, SSDs are faster, it is not a secret, so yes, probably. – mikewhatever Sep 06 '23 at 16:03
  • Thanks for the reply. Has anyone quantified the times for Linux/Ubuntu PCs? Just curious. – Trevor_B Sep 06 '23 at 17:52
  • Perhaps someone did, you are more than welcome to use a search engine to find out. I see no merit in such an exercise, as different computers are not made equal, but who knows... – mikewhatever Sep 06 '23 at 18:36
  • I upgraded my M.2 SSD to larger NVMe drive. Did not notice a huge improvement like I did when going from HDD to SSD. But these settings also make a large difference and what flavor you boot makes a difference. https://askubuntu.com/questions/1284302/is-it-possible-to-make-ubuntu-20-04-boot-faster I always do new install, use LTS versions and have two / (root) partitions and alternate install partitions. All data, but not /home is in separate data partition(s). – oldfred Sep 06 '23 at 19:51
  • Is this question open to other possible causes? Or are your sure that you only want to compare those two solutions? – user535733 Sep 06 '23 at 20:38
  • Excuse my ignorance, I havn't done a fresh install since 16.04 only upgrades. I was simply asking general advice on speed up due to a fresh standard install & HDD to SSD? I have no reason to suspect there is anything wrong requiring troubleshooting. HDD activity during boot is continuous not fragmented. – Trevor_B Sep 06 '23 at 20:47

A fresh install could improve your app load times, but the biggest improvement in boot and app load times would be achieved by changing to a new SSD and installing either Ubuntu 20.04 or the latest LTS version, Ubuntu 22.04, on it.

  • OK, thanks. It sounds like a move to SSD makes sense. You mention 22.04, I'd prefer to stick with 20.04 because my peripherals (optical drives, card reader, USB WiFi) & important apps (Asunder & Document-Scanner) work well with 20.04. With the move from HDD to SSD are there any electromechanical issues I should be aware of other than 3.5" vs 2.5"? – Trevor_B Sep 07 '23 at 07:48
  • I don't know of any electromechanical issues that you should be aware of, but to be on the safe side you could select the Try Ubuntu option of the Ubuntu installer to try Ubuntu in a live session before installing it. – karel Sep 07 '23 at 07:58
