Title: [Plugin: WP-FFPC] Memcache In Protocol Mode Binary Last modified: August 20, 2016 --- # [Plugin: WP-FFPC] Memcache In Protocol Mode Binary * Resolved [JustinK101](https://wordpress.org/support/users/justink101/) * (@justink101) * [14 years, 1 month ago](https://wordpress.org/support/topic/plugin-wp-ffpc-memcache-in-protocol-mode-binary/) * Changing memcache to run in binary protocol instead of ASCII breaks the plugin. * The directive is: memcache.protocol * Any ideas on this? * [http://wordpress.org/extend/plugins/wp-ffpc/](http://wordpress.org/extend/plugins/wp-ffpc/) Viewing 12 replies - 1 through 12 (of 12 total) * Plugin Author [petermolnar](https://wordpress.org/support/users/cadeyrn/) * (@cadeyrn) * [14 years, 1 month ago](https://wordpress.org/support/topic/plugin-wp-ffpc-memcache-in-protocol-mode-binary/#post-2684775) * [@justink101](https://wordpress.org/support/users/justink101/): I’ve never tried that setting to be honest. Can you please tell me a situation, where changing that parameter is really necessary? * Although the plugin should work, I’ll take a look into it, but seems to be a rare situation to use memcache in binary mode. * Thread Starter [JustinK101](https://wordpress.org/support/users/justink101/) * (@justink101) * [14 years, 1 month ago](https://wordpress.org/support/topic/plugin-wp-ffpc-memcache-in-protocol-mode-binary/#post-2684878) * Peter, * So we are building a high scale WordPress multi-site setup, and our memcache server is on a separate server from the web/php workers. Doing some benchmarks, the traffic between the web server and memcache server was reaching 40-60mbps. Read that using binary protocol results in much smaller network traffic. * Would you be able to assist me one-on-one for a bit? We could pay you for your time. * Plugin Author [petermolnar](https://wordpress.org/support/users/cadeyrn/) * (@cadeyrn) * [14 years, 1 month ago](https://wordpress.org/support/topic/plugin-wp-ffpc-memcache-in-protocol-mode-binary/#post-2684892) * Although it sounds great I have no idea yet how to even get started hunting the cause, but I do want to solve it 🙂 * Plugin Author [petermolnar](https://wordpress.org/support/users/cadeyrn/) * (@cadeyrn) * [14 years, 1 month ago](https://wordpress.org/support/topic/plugin-wp-ffpc-memcache-in-protocol-mode-binary/#post-2684894) * [@justink101](https://wordpress.org/support/users/justink101/): I’ve added * memcache.protocol=”binary” * but the plugin did not fail, it worked the save a before. Can you please tell me what did you experienced as breaking? * Thread Starter [JustinK101](https://wordpress.org/support/users/justink101/) * (@justink101) * [14 years, 1 month ago](https://wordpress.org/support/topic/plugin-wp-ffpc-memcache-in-protocol-mode-binary/#post-2684926) * Peter, * When we enable: * memcache.protocol = “binary” * We stop seeing the cached header in the response, and indeed its not caching in memcached. Can you confirm that when you running in binary, its still caching and working? * Thanks. * Thread Starter [JustinK101](https://wordpress.org/support/users/justink101/) * (@justink101) * [14 years, 1 month ago](https://wordpress.org/support/topic/plugin-wp-ffpc-memcache-in-protocol-mode-binary/#post-2684941) * Peter, * Here are additional details, maybe you can replicate. * **PHP Version:** 5.3.10 **PHP Memcache Version:** 3.0.6 **Memcached Version:** 1.4.13 * Thanks. * Plugin Author [petermolnar](https://wordpress.org/support/users/cadeyrn/) * (@cadeyrn) * [14 years, 1 month ago](https://wordpress.org/support/topic/plugin-wp-ffpc-memcache-in-protocol-mode-binary/#post-2684963) * Hi, * I’ll make some tests with binary protocol on an other machine as well to see if anything happens. * Thread Starter [JustinK101](https://wordpress.org/support/users/justink101/) * (@justink101) * [14 years, 1 month ago](https://wordpress.org/support/topic/plugin-wp-ffpc-memcache-in-protocol-mode-binary/#post-2684978) * Peter, * Wanted to follow up, and see if you can reproduce binary mode not working with WP-FFPC. * If we donate some money, do you think you can free up a bit of time to work with us on WP-FFPC for a bit. * Thanks. * Plugin Author [petermolnar](https://wordpress.org/support/users/cadeyrn/) * (@cadeyrn) * [14 years ago](https://wordpress.org/support/topic/plugin-wp-ffpc-memcache-in-protocol-mode-binary/#post-2685007) * Hi Justin, * No, I wasn’t able to reproduce the bug yet. To be honest, I did not have the time to put together a system with the versions you described, but I still want to figure this out, I just don’t really know, when. * My system is an Ubuntu 11.10, with the following versions: Memcached 1.4.7 ( from ubuntu package) PHP Memcache 2.2.6 ( 3.0.6 is still beta, that’s the reason) PHP Version 5.3.6-13ubuntu3.6 * … and now I see that the reason I’m unable to reproduce it is that I’m using pre 3.0 version of PHP-Memcache. * I’m going to upgrade it and get back to this problem. * [pepejose](https://wordpress.org/support/users/pepejose/) * (@pepejose) * [14 years ago](https://wordpress.org/support/topic/plugin-wp-ffpc-memcache-in-protocol-mode-binary/#post-2685015) * sorry for post but i cant create new topic 🙁 * hi! (sorry for my poor english) * my install: * nginx php-fpm php 5.3 memcached memcache librarie * wordpress 3.3.2 multisite install (sub-directories) Networks for WordPress plugin * I have three networks and I activated wp-ffp on one of them (have 2 blogs in that network), in the configuration I have enabled “Enable debug mode” but I dont see the header “X-Cache-Engine” in the response headers. also I dont see errors in php. seems like plugin was not activated * in the plugin configuration page, I see Backend status: up & running * any help please!? * thank you very much * Plugin Author [petermolnar](https://wordpress.org/support/users/cadeyrn/) * (@cadeyrn) * [13 years, 9 months ago](https://wordpress.org/support/topic/plugin-wp-ffpc-memcache-in-protocol-mode-binary/#post-2685033) * Hi [@pepejose](https://wordpress.org/support/users/pepejose/), * I’m sorry, I didn’t have any time to retouch the plugin until now. Actually I’m unable to figure out the memcache modul & binary mode error, it seems to be deeper than my plugin. * But! Eventually I’ve made a progress and made the memcache**d** modul to go with binary mode and be compabible with nginx as well – if you could use that, that may help you. * Cheers, Peter * Plugin Author [petermolnar](https://wordpress.org/support/users/cadeyrn/) * (@cadeyrn) * [13 years, 5 months ago](https://wordpress.org/support/topic/plugin-wp-ffpc-memcache-in-protocol-mode-binary/#post-2685048) * Seems that memcache module has a serious bug using binary mode; I’m closing this topic, binary mode is default with the plugin using memcached and not supported using memcache.
