After much effort I upgraded our fairly large Rails app from 2.1 to 2.3. After deployment yesterday I noticed an across the board increase in response times. It seems that every call to memcache now takes 10x longer than before. Here are some example numbers from my development log (below), with memcache running locally. We see similar scale of performance drop in production as well - average memcache call before 2ms, now 20ms. It adds up to a significant hit.
Before Rails 2.3 upgrade: Cached fragment hit: views/homepage_recent_blog_posts (0.00043) Cached fragment hit: views/homepage_active_threads (0.00033) Cached fragment hit: views/homepage_weekly_feature (0.00029) Cached fragment hit: views/homepage_recent_approved_items (0.00036) Cached fragment hit: views/homepage_popular_items (0.00037) Cached fragment hit: views/number_of_members (0.00032) After Rails 2.3 upgrade: Cached fragment hit: views/homepage_recent_blog_posts (3.2ms) Cached fragment hit: views/homepage_active_threads (3.5ms) Cached fragment hit: views/homepage_weekly_feature (2.9ms) Cached fragment hit: views/homepage_recent_approved_items (2.8ms) Cached fragment hit: views/homepage_popular_items (3.1ms) Cached fragment hit: views/number_of_members (6.7ms) Before I start delving into the memcache internals in Rails 2.3, has anyone else experienced this degradation on their apps? Is there a magic 'make it fast again' switch that I can flick? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
