无法理解为什么我的 rails 应用程序变得超慢 - 在 1 分钟内！
正如我所看到的总时间 Rails 应该是：视图 0.2ms + 活动记录 219.5ms + Solr 379.7ms = 599.4ms
但是它需要62615ms，其余时间62015.6ms在哪里？

找到速度变慢的原因。 我们团队中的某个人将延迟服务添加到控制器中。
在config/environments/development.rb中注释#require 'sidekiq/testing/inline'并单独运行sidekiq -C config/sidekiq.yml它解决了问题后，现在服务正在异步运行。
但是问题出在服务内部，调用RestClient.post(endpoint, payload.to_json, 'api-key': api_key)被包装到捕获错误的块begin rescue end(在 RestClient 超时后一分钟内引发)。
