My Acer Aspire One netbook is good but the 8GB SSD drive that it shipped with is still the biggest drawback. When I want to view HQ or regular YouTube clip (forget about HD), the SSD gets accessed and performance takes a dive. Videos stutter and playback is horrible.
The first tweak is to mount the SSD switching the option from “relatime to “noatime”.
From the article:
Tweak #3: Change the file system mount options on SSDs to “noatime”. On certain Linux distributions, such as Ubuntu, the default is “relatime”. This tells the kernel to write the Last Accessed Time attribute on files. Conversely, “noatime” tells the kernel not to write them, which considerably improves performance. Linus himself suggests using it in circumstances such as this, so therefore, I consider it to be gospel.
The second tweek is on the kernel line in /boot/grub/menu.lst, right after splash, insert the option “elevator=noop”. This will let you use the “noop” I/O scheduler. The SSD is not a hard disk and there is no platter to optimize.
These combined reduces the amount of writes to the SSD and I am now able to view this whole episode of Gundam 00 in HQ. Before these changes I could not have done this.
Considering that my main desktop PC is dying and needs to be replaced, having an optimized netbook is not a bad thing at all.
