It's a Saturday and I am kinda bored. So I thought I'd explain my tweet a few days ago.
- I was kicked to find out that the Atom chip my puny laptop has is a 64-bit processor. I wiped out the 32-bit Ubuntu I was running and installed 64-bit version of it. I don't know the internals of Linux, but it looked like the 64-bit kernel was swapping too much. My machine has 2GB RAM. Even when half of the physical RAM is free, the machine would be using around 0.5 to 1 GB of swap space. It was unusably slow, I reverted to 32-bit Kubuntu. It doesn't swap stupidly any more. (On the other hand, 64-bit kernel runs fine on my machines that have 8 or 12GB RAM. Maybe 64-bit works well on machines that have a lot of RAM.)
- I was cribbing about bad wireless performance of my Galaxy Tab, and someone suggested that I use the n channel of 802.11 on my home wireless router. I made the switch and the experience just got worse. Maybe it was the router's 802.11n implementation that sucked. After reverting to 802.11g, it's better now.
