I have just built LFS 6.4 and am in the process of ironing out some kinks. I ran a simple minded performance check, by simply copying the LiveCD to /dev/null, and comparing that with /dev/zero -> /dev/null.
dd if=<source> of=/dev/null bs=1024 count=636340 Source real user sys ------ --------- -------- -------- 52x CD 31m6.06s 0m0.176s 0m4.918s That looks like I've got non-optimal driver there. Anyway, I'm going to try this test again booted with the LiveCD and see how fast it runs. Could just be the small block size. In an attempt to discover what is under the hood on this machine without peeling back the hood and trying to decipher chip markings, I might use /proc when the system is booted with the LiveCD. ISTM that for someone who knew what he was doing, it wouldn't be too hard to write something that could convert that info into recommendations for kernel config. Just a thought.
