Faster WP Super Cache with NginX

Once I had run the namebench too again, the results were showing a huge leap in performance. But strikingly, BT’s DNS servers were still faster than my own local servers. Jonathan, the resident monkey, also commented about this based on his own tests. It seems that there might be something amiss with the namebench tool (and I shall dutifully point this out to Google, to see what they have to say). read more →

In fact, this is the damning message that namebench gave me: read more →
