Update.1 690 very slow on B2-7 XO

[Zvi Devir]

The main problem with B2 is memory, not CPU speed. You can speed up your 
B2 machine by using the swap as the missing memory:
* Plug a USB2 storage device
* mkswap the device (mkswap /dev/sda1)
* Activate the swap (swapon /dev/sda1)
Technically, you can update fstab for automatic swap. Practically it's 
more complicated, and failed to automate the swap this way.

Cheers,
