Any comments on this: http://www.denx.de/wiki/Know/Linux24vs26
On another denx.de page I found this summary (so you do not have to visit the page): # slow to build: 2.6 takes 30...40% longer to compile # Big memory footprint in flash: the 2.6 compressed kernel image is # 30...40% bigger # Big memory footprint in RAM: the 2.6 kernel needs 30...40% more RAM; # the available RAM size for applications is 700kB smaller # Slow to boot: 2.6 takes 5...15% longer to boot into multi-user mode # Slow to run: context switches up to 96% slower, local communication # latencies up to 80% slower, file system latencies up to 76% slower, # local communication bandwidth less than 50% in some cases.
I'm merely asked because I have been pointed to this page several times and I do nto have numbers for 2.4 versus 2.6.
Note: denx does support 2.6 now.
I do not concur and recommend 2.6 but wanted to know if anyone had more insight to share.
