Maybe we need to come over and tie him up?

I have replaced PHP5-FPM with HHVM. The first reference to a PHP file should be slower than with php5-fpm, but all subsequent much faster. Probably it will not be noticeable. But HHVM multithreaded and takes much less memory than separate PHP5 processes.

Please let me know what you see/feel/experience.

Speaking of the KVM vs Xen performance again, here's the disk IO load:

   

Nice, eh? 😉

I removed the preparser cache and now the thumbnails are loaded correctly. Meed to properly investigate this later...

I'd be surprised if anyone understands. I certainly don't 😊

It's about a virtual server that dances real old school hiphop!

Yes, my first vacation day.... And #-&$#@@$@$ WordPress decided to automatically upgrade, what apparently broke the DB tunings I made, and trashed the HHVM cache. Or something else. Just rebooted the server, looks OK so far. Thanks to Linode such things are possible from a smartphone.

#-&$#@@$@$

And #-&$#@@$@$ happened again. Rebooted the box... That definitely does not make happy....
