Re: Defrag - firenice03 - 09-06-2016

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  Wink

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.freecinema2022.gq/forums/network/(solved)-broadcom-wireless-issue/msg4997/#msg4997
But searching will result a lot of results.. Again if the slowness is network related  :o

I was posting the same time as Jerry... Or as he suggests....

I concur with Jerry.
I think that HD is a significant source of performance issues...
Benchmark for Hitachi HT54505

I think any recent SSD is going to be a major boost.

You are only using 3.7% of 500GB, so even a cheap 120/128GB would be enough

Re: Defrag - Wirezfree - 09-06-2016

@firenice03 raises some good points

Are you seeing laggy internet..??
What does a speed test give you.?

With that CPU you should not have issues really
Benchmark for: AMD A6-3420M

On my N3700 I get to the desktop from cold boot in @ 10~12secs with a SSD


I think your disk is a bottleneck

Just to check on the HD as likely culprit, go to Disks, press CTRL+S, and look over your SMART Data.
Curiosity kills the cat.

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 Disk
Code:
sudo hdparm -t /dev/sdb
/dev/sdb:
Timing buffered disk reads: 332 MB in  3.00 seconds = 110.57 MB/sec

On Samsung SSD
Code:
sudo hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 1494 MB in  3.00 seconds = 497.68 MB/sec

This is what I got:

It's O.K, but 5 to 6X slower than an SSD

I've installed a virtual machine do you think it's possible to run it with this specs? I'm planning to install windows in it.

Hmm.. I wish I can explain it more accurately. It's not slow like a speed of a car, it's more laggy for example minimizing a browser it tends to leave some kind of trail some sort of a shadow.
