Puppy2 Alpha Sea Monkey Boot Times

[JustGreg]

I did some measurements of boot time for different configurations
of Puppy. Puppy allows one to carry it from different machines.
This portability is something that apeals to many people. It
is one the reasons I looked at the booting of USB devices.

The measurements were to help me make a decision on the
configuration that I will use when the Puppy2 comes out of
testing. The time was measured from the appearance of the
BIOS boot screen to the time the full JWM screen.
I am sharing this with the community for their
use. I provide information on Puppy 1.0.7 (the version, I
use the most) and Puppy2 Alpha Sea Monkey.

Booting from a IDE partition with Grub gives:
Puppy 1.0.7 boot time of 34.4 seconds,
Puppy2 Alpha boot time of 36.8 seconds.

Booting from a Puppy2 Alpha CDROM and USB flash drive for
save file gives a boot time of 95.2 seconds.

Booting from a USB device gives:
Puppy 1.0.7 512 Mbyte Sandisk boot time of 235 seconds,
Puppy2 Alpha 512 Mbyte Sandisk boot time of 205 seconds,
Puppy2 Alpha 1 Gbyte Kanguru boot time of 109 seconds.

I hope this helps.

Booting from a USB device gives:
Puppy 1.0.7 512 Mbyte Sandisk boot time of 235 seconds,
Puppy2 Alpha 512 Mbyte Sandisk boot time of 205 seconds,
Puppy2 Alpha 1 Gbyte Kanguru boot time of 109 seconds.

That's very interesting, I wonder why such a big difference?
The Sandisk and Kanguru are both usb2 interfaces?

[JustGreg]

Yes the difference is striking. I noticed it other file operations,
boot really shows it. At Bios boot screen, the Sandisk flash drive reports more information than the Kanguru hard drive. The Kanguru only reports "usb ide bridge". I do not known enough about USB to say anything. But, I suspect that the "usb ide bridge" may have something to do about it.

There have been a couple of reports on USB read/write speeds that showed dramatic differences between flash drives of various makes (all were USB 2.0).
One report can be found here.

Speed differences of up to three times give food for thought.
