I've installed it on 40Gb hard drive with 1Gb swapfile and all other space as root partition in btrfs. Entire installation process took too much time, but I thought that it's due to limited amount of memory. But when the system booted I've found that It used only 50Mb and 50Mb were in swap. It was constantly swapping, as soon as system tried to get some memory for newly starting application. And swap usage was almost the same as memory usage. That is, when 100 Mb of memory was used, swap was used for about 100Mb etc. Buffers took about 40Mb. Booting process took about 3 minutes. System was almost unusable since it was slowed down so much. I've tried changing swappines from 60 to 10 but that had absolutely no effect. So, I had to remove that system and install LTS version with LXDE and it works pretty fast. Sorry for not providing ubuntu-bug data. I forgot to do that, but now that system is removed. But I think that this bug is too important to ignore. P.S: I've experienced something very similar on another machine when used someone's build of cfs kernel. --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
