New Blog Location / IPv6 Hacking – “thc-ipv6” [Part 1]

I’m pleased to announce the first post in my blog’s new location, here at keepingitclassless.net. I have been running a casual blog from my house for the past two years with mixed success.

Benchmarking OpenBSD: UP vs MP for “make build”

I used to have a machine sitting around that I would power up whenever I needed to build a new OpenBSD kernel or rebuild the source tree due to a patch or a new version of the OS being released. Eventually I moved that machine into a VirtualBox virtual machine running on my desktop. Recently I moved that VM into VMWare's free ESXi hypervisor running on some pretty decent hardware. It got me wondering how much I could lower compile times by adjusting how many vCPUs were allocated to the VM.
