For those of you running mod_ruid2, what advantages have you gained over the older Apache configurations? I'm tempted to do a recompile, but as this is a live server, don't want to risk the downtime if things head south.
I've been using mod_ruid2 for a while now (June 2012). It means you can use APC/Xcache correctly, while still keeping different hosting accounts separate.
Matt, did you run into any issues with mod_security after you changed over? I've read about a few issues on other sites, but I'm tempted to chalk it up to the experience (or lack thereof) of the administrator doing the changes.
I use the Atomicorp rules and I've turned off the 3 or 4 rules that were causing issues with the membership and all seems to be going well. I check the logs religiously to ensure I'm not blocking legitimate user traffic. I don't think I've blocked a legitimate user in ages now.
