Ubuntu 10.04 (Lucid Lynx) boots fast

A few  days ago, I installed Ubuntu 10.04 (Lucid Lynx) on my Super Talent Ultradrive GX 64GB (firmware version 1916 with TRIM support) and rebooted it thirty times to get some data from bootchart. Here are the results: The fastest boot took only 3.65 seconds. Impressed?

The default installation averages out at 4.5 seconds. The highest disk throughput was 204 MiB/s (thanks to ureadahead).

After everything was installed, the boot takes six seconds (probably due to liferea).

A SSD leads to a fast booting system, but then the processor has an impact on boot times too. Compare these boot charts with the one of the IBM ThinkPad T400. The SSDs are similar, but the processors differ: Core 2 Duo E8500 @3.16GHz versus Core 2 Duo T9400 @2.53GHz.

Do your system boots faster?

7.35 seconds for booting

Today I had to set up a new Lenovo IBM ThinkPad T400. I replaced the hard drive by a Super Talent Ultradrive GX2 128GB and extented the memory to four gibibytes. The installation of Ubuntu 10.04 (lucid) took four minutes (time after answering questions and before rebooting to installed system). The notebook is fast with the SSD. After pressing the power button, the system needs nearly 20 seconds to reach GRUB. 7.35 seconds later the GNOME desktop is ready for usage.

Plymouth is nice, but it’s gone before it appears. The system boots too fast for plymouth. But why do I have to stare at plymouth quite a few seconds on shutdown? Shutdown shouldn’t take longer than boot.
