Natty Narwhal boot times - What has changed?

Filed under
Ubuntu

In my Natty review, I did mention that boot times seem to have changed considerably compared to previous versions of the distro. In other words, they got longer, which is kind of surprising as the desktop is quite fast and snappy. I had no numbers to quantify my feeling then, but now I do. Using Bootchart, I profiled the boot times on Natty. So let's see what happens. Moreover, we'll check if there's anything we can do to make things better.

Previous benchmarks

Before we take a look at Natty, let's see what we had in the past. With Lucid, testing on three machines, T42, T60 and RD510, I managed 27, 15, and 26 seconds, respectively. On my HP machine with a 7,200rpm disk, the boot time is about 17 seconds. On a laptop with SSD and running Maverick, the boot time ranged between eight and nine seconds, which is quite reasonable overall. All right, let's see what happens with Natty.

Teaching open source changed my life

Teaching open source has been a breath of fresh air for myself and for many of our students because with the open source way, there are no official tests. There is no official certification for the majority of open source projects. And, there are no prescribed textbooks. In open source, no employer worth working for will ask for official proof of your abilities. A good employer will look at what you’ve done and ask you to showcase what you can do. Yes, it still helps to have a Computer Science degree, but the lack of one is often no drawback. Read more

KDE Touchpad configuration ported to Frameworks 5

Fedora 20 with KDE SC 4.14 has been very stable, and after a while it gets…boring – especially when Plasma 5 is already released and you see screenshots everywhere. If you cannot hold the urge and feel sufficiently adventurous, Dan Vratil has built the Fedora 20 and 21 rpms here. If you install i386 versions, beware that baloo-widgets cannot be installed due to unmet dependencies. So, once you install dvratil’s copr repo, just do: Read more

Intel P-State vs. CPUFreq Benchmarks On The i7-5960X

Testing was done with the Intel Core i7 5960X at stock speeds. The Linux 3.17 Git kernel atop Ubuntu 14.10 was used for this round of testing. The Core i7 5960X has eight physical cores plus Hyper Threading, 3.0GHz base frequency, and 3.5GHz turbo frequency (that's the reported difference in the system information table due to P-State advertising the turbo frequency where as CPUFreq just reports the base frequency).
