<br>
so reporting back that this seems to have definitely had a significant <br>
positive effect.<br>
<br>
So far today I have not seen the load average climb over 13 with the <br>
15minute average hovering around 7. cpus are still spiking from time to <br>
time, but they are not staying maxed out all the time, and frequently I <br>
am seeing brief periods of up to 80% idle. glusterfs process still <br>
spiking up to 180% or so, but consistently running around 70%, and the <br>
brick processes still spiking up to 70-80%, but consistently running <br>
around 20%. Disk has only been above 50% in atop once so far today when <br>
it spiked up to 92%, and still lots of RAM left over. So far nload even <br>
seems indicates I could get away with a 100Mbit network connection. <br>
Websites are snappy relative to what they were, still a bit sluggish on <br>
the first page of any given site, but tolerable or close to. Apache <br>
processes are opening and closing right away, instead of stacking up.<br>
<br>
Overall, system is performing pretty much like I would expect it to <br>
without gluster. I haven't played with any of the other settings yet, <br>
just going to leave it like this for a day.<br>
<br>
I have to admit I am a little bit suspicious. I have been arguing with <br>
Gluster for a very long time, and I have never known it to play this <br>
nice. kind feels like when your girl tells you she is "fine"; <br>
conversation has stopped, but you aren't really sure if it's done...<br>
