php7 + memcache: stable?

We'd like to run our Drupal 7 sites with php7. The only trouble we have so far has to do with the PECL memcache(d) extensions - no stable release supporting php7 has been published yet:

<

ul>

  • The PECL/memcached package is being discussed in this issue where people are actively waiting for a stable release to move to php7 (some of them ended up moving to Redis because it was taking too long)

    Personalisation / Custom caching

    Hi all,

    I want to build a module that handels caching and is able to deal with altering pieces of content based on some variables.

    For a client we've developed a D7 site a couple of years back. The site is high-traffic and serves a lot of visitors but only anonymous users. The site uses views, panels and panels everywhere for it's layout, general pagecaching for cache and all media comes from a CDN. Everything works great!

    Should I still use entitycache in Drupal 7 projects?

    I have been using entitycache [1] without problems in D7. However I have not really measured lately does it really improve the performance and is there some issues? And what is the state at the moment about entitycache going to core [2] in D7 or D8?

    What I am asking is:

    1. Should I use entitycache in projects of any kind? (Like using APC cache ALWAYS because it does not matter is there logged in users or not.)

    2. Has anyone measured the impact lately? (If it is in core it does not really make sense using it, right?)

    APC regularly restarts after 10-20 minutes

    <

    p>I have a site running Pressflow (Drupal 6), Varnish, Memcached, and APC with the Cache Router module. I'm unsure why but APC is restarting every 10-20 minutes. If I review the stats page (see the attached image) the uptime will increase to somewhere between 10 and 20 minutes. As I click the "refresh data" button I'll see a second cache set shown with an uptime of 0 or 1 minute, and each click of refresh data will toggle between uptime of 15 minutes and uptime of 1 minute. Eventually the 15 minute uptime disappears and I only see the 1 minute uptime...

    Unusual characters not loaded in Boost static cache

    (Setup: Drupal 6.20, Boost 1.18, Nginx 0.7.67)

    When the URL of the boosted node contain character or 中国新闻网新闻中心, the cached node is correctly cached in the cache directory, and correctly reflecting the URL.

    But when accessing the node, the uncached node loaded instead.

    Below is the Nginx rules I use:

    server {
        server_name *.com *.net *.org;
        location / {
            root   /var/www/html/$host;
            index  index.php;
            set $boost "";
            set $boost_query "_";
            if ( $request_method = GET ) {

    Caching content for authenticated users

    Exove Ltd is developing a new module, integrating Varnish into Drupal in a way that allows caching not only anonymous users' content, but authenticated users' content as well.

    The basic idea behind the module is to generate cacheable anonymous versions from any page with cacheable content, leaving placeholders in place of user specific content, and to serve those versions to all users. Any user-specific content is then replaced with AJAX for all authenticated users.

    Best caching for thousands of authenticated users?

    Hi.

    Currently I'm developing drupal page (as knowing drupal on medium+ level) for ONLY authenticated users.

    Aim is to get even more than 1 mln loged in users.

    Site will be quite simple. Users can add some nodes, that are visible ONLY for their friends. Users can search (currenlty using views filter) for a node (still ONLY their friends nodes), and can watch others friends profile (with nodes friend submitted).

    I think that all page should be cached exept searching result. And if a user submitted a new node his profile should be updated (cache cleared).
