由 流过昼夜 提交于 2019-12-07 04:56:12
问题 Here's the deal. We would have taken the complete static html road to solve performance issues, but since the site will be partially dynamic, this won't work out for us. What we have thought of instead is using memcache + eAccelerator to speed up PHP and take care of caching for the most used data. Here's our two approaches that we have thought of right now: Using memcache on >>all<< major queries and leaving it alone to do what it does best. Usinc memcache for most commonly retrieved data,

由 瘦欲@ 提交于 2019-12-07 04:03:53
问题 I hope someone can help me with a problem that I am certain is a user error. The configuration details below work in all my other environments including integration, development and qa.

GAE: memcache: is it the same across multiple app instances

由 試著忘記壹切 提交于 2019-12-07 02:50:18
问题 I have a pretty basic question: In GAE, if I use memcache to store some data once it was retrieved for the first time from the db, if then that data remains in the cache for like 2 days, do ALL instances of said application get to "see" it and retrieve it from cache? Or is the cache separate for each application instance? I'm asking this because I've seen that due to the way that GAE spawns separate VM processes (not threads) for each new instance an application needs, stuff that used to be

Failed to write session data, php and memcached

由 孤街醉人 提交于 2019-12-06 18:19:48
问题 I have recently tried implementing memcached for session saving in php. I modified the session.save_handler in my php.ini and for the most part it works correctly. Sessions are saved in it. However, once in a while, I get this weird message for certain sessions: PHP Warning: Unknown: Failed to write session data (memcached). Please verify that the current setting of session.save_path is correct (x.x.x.x:11211) in Unknown on line 0. The session data is the same, way under the 1MB barrier of
