PHP via FCGI with PHP opcode and object caching
Hello all,
I am running (and developing) a site that runs on multiple (app) nodes behind a load balancer, and a separate database and storage server. Each node runs Apache (MPM worker) with FCGI, APC turned on. Drupal 7 based, with the APC module enabled, with most cache tables deferred to APC.

APC fragmentation and miss rate / Cacherouter
I am trying to tune apc for improving sites performance.
I use cacherouter and set it to redirect all cache tables to apc (see below)
apc stats and data are available for example here:
https://www.see.asso.fr/apc.php
I observe that the fragmentation is high despite a significant memory allocation, and the miss rate is exactly equal to the insert rate for File cache and much more for user cache
Is everything fine, or should I expect better, how?
Thanks for comments, help, suggestions

Increasing remote participation at the monthly High Performance Drupal meetups
Hi, fellow performance nuts. We're planning the next High Performance Drupal meetup in Los Angeles, California, and I'd like to coordinate with everyone here in the larger group to see how we can boost our online attendance.
What would make this meetup more interesting and accessible? What's working for your user groups and other organizations with online tech events and webinars?
The highest number of remote attendees we've had so far is 7 when mikeytown2 presented on HTTPRL (and mikeytown2 himself presented remotely). Recently, that number of remote attendees has been hovering around 2.
This is pretty good attendance for a specialized topic such as Drupal high performance, but in comparison we've consistently had between 15-20 people from the Los Angeles area attend in person and I'm not sure how to cater more to those who'd like to attend (and present) remotely.
Possible problems ^
The reasons that I can think of that our remote attendance has been lower than expected are:

Authcache: 1.0 release & "multi-variant" caching
Hi All,
Thought you might be interested to know that I've just posted a 7.x-1.0 release of Authcache.
I've also added an interesting feature to the dev branch. That is, the ability to have custom authcache keys. This might be useful for example if you have a lot of roles on your site but you don't want to cache different content for each of them. It would also be useful if you wanted to cache different content for different devices eg mobile / desktop etc.
It's very easy and powerful.

Liquid Web Storm Servers VPS -- Would you recommend?
I've been asked by a client to get references for Liquid Web and their Storm Servers VPS solution, but I'm not able to get any through Liquid Web themselves. Can anyone recommend them, or does anyone have bad experiences? Thanks!

XML Sitemap Scan = high load
Yesterday, an internal staff member was running two XML sitemap scans on our site and we were seeing loads on the Linux web head servers in excess of 12-15. We are running a Varnish/Pound proxy in front of the drupal web head with the MySQL DB on a 3rd server. We asked them to stop and the load disappeared.
