<br>
<br><font size=2 face="sans-serif">While performing some zttest's for some
time today, I was also keeping an eye of a top of the machine. While
the zttest was running, I also had a ssh-keygen and a dd creating a 5GB
file on an EXT3 partition running. I noticed that for the most part,
I got a decent number of 100%'s, and a bunch of 99.6%'s or higher. However,
it seems that whenever the zttest dropped below 99%, it was usually (or
at least often) because kjournald was jumping up in the top list.</font>
<br>
<br><font size=2 face="sans-serif">Has anyone done a comparison of zttest
results with journalled and non-journalled file systems? From my
very limited testing today, it seems like that might be an area to investigate.
Does anyone have any suggestions on how one might best test this?
Or adjustments that might be made to journalling settings that might
improve this?</font>
