Translating learns it has a Intel Core i3-2367M CPU with Intel HD Graphics, and 4 GiB RAM. The i3-2367M is an ultra-low power dual core processor at 1.4 GHz, and it has the HD 3000 IGP. This is from the Sandy Bridge series.
As to performance, you can perhaps gain some performance (at least shorten boot time) by disabling some services you don't need:

viewtopic.php?f=59&t=113043). To do this, edit your /etc/default/grub file:
- Code: Select all
sudo nano /etc/default/grub
Scroll with the down arrow key till you find the line:
- Code: Select all
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Then add the i915.i915_enable_rc6=0 boot parameter at the end, like so:
- Code: Select all
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.i915_enable_rc6=0"
Save and close the file (Ctrl+O, Enter, Ctrl+X). Then activate your changes and upon next reboot you should have no more crashes:
- Code: Select all
sudo update-grub2
