Linux Version 2.6.39 once again took Linus Torvalds and his fellow developers less than 70 days to complete. This is further indication of a slight, though ever more apparent, increase in the kernel's development speed, as about 80 to 90 days still passed between the release of two versions one or two years ago. With 2.6.39, this also meant that there was a slight decrease in the number of advancements which are worth mentioning in the Kernel Log; however, there are still plenty of changes that will make Linux faster and better.

Hi,

Some interesting stats:
- 1991 Linux kernel started
- 1996 (5 years later) "Big kernel lock" added as a quick hack to get it working on SMP systems
- 2011 (15 years later) "Big kernel lock" finally removed completely

It would've been quicker to rewrite it from scratch in 1996, instead of attempting to retro-fit SMP support on a kernel that wasn't originally designed for it; especially when you consider that the number of contributors would've been far less in the earlier years.

Just 8 years longer than what transpired on FreeBSD.
