I have two machines, both acting as clients & servers. Below are the fully
loaded configs, using server side unify over afr with various performance
translators. As you'll see I'm using glusterfs for the /home dir. In users
home directories I have php based websites that are being served by apache .
The loading of the web pages is very slow compared to using non-gluster file
systems on the same machines. I was concerned that perhaps using glusterfs on
top of software raid might be the issue. But if that's known to *not*
significantly impact performance, then perhaps I should be looking at another
way of building this config? Thanks for any insight.
