Hi, I have FreeBSD 8.2, and I run bsdtar all works well(bsdtar takes 6 sec) Now if I run md5 on all files under /lib and after again run bsdtar again with exactly same parameters as the first time, it takes 40 times long time to execute (240 sec approx.). Now this situation will not change until I reboot the system. I mean I can run bsdtar as many times as I wanthere t the time it takes is always 240 sec. If I reboot the system the all can be repeated. I have tried to move the files to different places but nothing helps. I also can see that while the slow bsdtar runs there are thousands of unvonlutary context switch and the cpu load is 100%. However the cpu is not doing anything else than running bsdtar. Any ideas?

Ok, that wasn't that hard. I got accents to work when using ee, I also got the "ø" to work, but I don't know what caused that, I think I had a wrong scrnmap in my /etc/rc.conf Here it is if someone wants to use it: It looks like making code page 850 will be a little more work, maybe I'll do that later. # $FreeBSD: release/10.0.0/share/syscons/keymaps/norwegian.iso.acc.kbd 2014-06-16 # Norwegian with accents.
