The poster thought that it seemed that the 2.4 kernels were being released faster than their 2.2 cousins at the same time period. Well, I took a look, based on timestamps on kernel.org: 2.2: Jan 26 1999 linux-2.2.0.tar.bz2.sign Jan 28 1999 linux-2.2.1.tar.bz2.sign Feb 23 1999 linux-2.2.2.tar.bz2.sign Mar 9 1999 linux-2.2.3.tar.bz2.sign Mar 23 1999 linux-2.2.4.tar.bz2.sign Mar 29 1999 linux-2.2.5.tar.bz2.sign Apr 16 1999 linux-2.2.6.tar.bz2.sign Apr 28 1999 linux-2.2.7.tar.bz2.sign May 11 1999 linux-2.2.8.tar.bz2.sign May 13 1999 linux-2.2.9.tar.bz2.sign Jun 14 1999 linux-2.2.10.tar.bz2.sign Aug 9 1999 linux-2.2.11.tar.bz2.sign Aug 26 1999 linux-2.2.12.tar.bz2.sign Oct 20 1999 linux-2.2.13.tar.bz2.sign Jan 4 2000 linux-2.2.14.tar.bz2.sign May 4 2000 linux-2.2.15.tar.bz2.sign Jun 7 2000 linux-2.2.16.tar.bz2.sign Sep 4 2000 linux-2.2.17.tar.bz2.sign Dec 11 2000 linux-2.2.18.tar.bz2.sign Mar 25 19:26 linux-2.2.19.tar.bz2.sign There were 5 months with multiple kernel releases, and 11 kernels released in those months which were all before 2.2.13 was released. Four of those months were before 2.2.9, counting May, with a corresponding 8 kernels released. 2.4: Jan 4 2001 linux-2.4.0.tar.bz2.sign Jan 30 2001 linux-2.4.1.tar.bz2.sign Feb 22 2001 linux-2.4.2.tar.bz2.sign Mar 30 05:03 linux-2.4.3.tar.bz2.sign Apr 28 01:43 linux-2.4.4.tar.bz2.sign May 26 01:26 linux-2.4.5.tar.bz2.sign Jul 4 00:07 linux-2.4.6.tar.bz2.sign Jul 20 21:25 linux-2.4.7.tar.bz2.sign Aug 11 04:13 linux-2.4.8.tar.bz2.sign Aug 16 18:32 linux-2.4.9.tar.bz2.sign There have been 3 months with multiple kernel releases, and 6 kernels released in those months. Also, 2.2.9 was released in May, while 2.4.9 was released in August. Another interesting note, 2.3.0 was released in May when 2.2.8 was current, but 2.2 releases didn't slow until 2.2.{12,13} was released. These numbers in no way try to determine how much actual development was done on each series in a time period. I also didn't factor in lkml email traffic in those time periods, but that doesn't really tell how much work was done either. Some interesting numbers may come from listing the number of patches submitted during each time period. Anyone interested? Mike
