I am just running a new series of response tests, which I expect to send
to the list today or tomorrow. It includes operating at some high
(LA>20) loads, and gathering reproducible statistics. In the process I
used the file completion feature while load was high, and noted that
with sd0.48 typing the first characters and hitting tab was VERY slow
compared to cfs12 or even fc6 recent release. The directory had about a
dozen files, there was only one match, and I was just saving typing a
long filename.
This was tested over three boots of sd0.48, cfs12, and fc6, as well as
one boot of cfs9, and the problem was only with the most recent sd
kernel I have built.
Hardware: Intel Core2duo 6600, 2.4MHz, 2GB mem, 600GB RAID5, kernel
2.6.21 build with "make -j20" to generate the load.
