As a Bulldozer owner, this sucks. I know a lot of attention is given to Intel processors, but AMD could use its fair share of attention.

Anyways, could you do a comparison test between the 8150 and the I7 2600k/ivy bridge? I want to see the increase in performance before upgrading to a intel machine.
Try this: switch to tty1. Login. Launch htop, note memory and swap usage and go away. When you return, check memory and swap usage.
Also check for HDD activity. Perhaps cirtain components were removed from memory as not needed anymore, due to not being adressed. If you claim its CPU, the memory load should be same and hdd should not be accessed intensively while you login back.

Also ever tried gentoo linux (everything compiled with march=native) ? This would be some benchmark I would like: Ubuntu vs Gentoo on AMD Bulldozer (and AMD Phenom II as reference).

Test with another CPU

Useless benchmark
It is a useless benchmark because the CPU isn't compared against any other CPU.

Phoronix: AMD Bulldozer Performance On Ubuntu 12.10
For those having computers with AMD FX "Bulldozer" processors, here are some benchmarks showing some of the performance improvements made -- and regressions -- in upstream GCC and the Linux kernel that can be found when upgrading to the forthcoming Ubuntu 12.10.
