ruby-prof
Gemfile:
gem 'ruby-prof'
然后在application.rb 中增加中间件
config.middleware.use Rack::RubyProf, :path => './tmp/profile'
就会生成好多文件，放到 ./tmp/profile文件夹下
/your_app/current/tmp/profile$ ls -call_stack.html members-20210-update_is_able_to_login-flat.txt members-42014-update_is_able_to_login-graph.html members-43604-edit_inviter_code-graph.txt -flat.txt members-20210-update_is_able_to_login-graph.html members-42014-update_is_able_to_login-graph.txt members-43611-edit-call_stack.html -graph.html members-20210-update_is_able_to_login-graph.txt members-42237-member_account_statistics-call_stack.html members-43611-edit-flat.txt -graph.txt members-28412-call_stack.html members-42237-member_account_statistics-flat.txt members-43611-edit-graph.html account_verifications-call_stack.html members-28412-edit-call_stack.html members-42237-member_account_statistics-graph.html members-43611-edit-graph.txt account_verifications-flat.txt members-28412-edit-flat.txt members-42237-member_account_statistics-graph.txt members-43611-edit_inviter_code-call_stack.html account_verifications-graph.html members-28412-edit-graph.html members-42319-edit-call_stack.html members-43611-edit_inviter_code-flat.txt account_verifications-graph.txt members-28412-edit-graph.txt members-42319-edit-flat.txt members-43611-edit_inviter_code-graph.html charts-members_upload_idcard-call_stack.html members-28412-flat.txt members-42319-edit-graph.html members-43611-edit_inviter_code-graph.txt charts-members_upload_idcard-flat.txt members-28412-graph.html members-42319-edit-graph.txt members-43612-edit-call_stack.html
然后就可以查看里面各种进程的调用情况。
不过还没发现 跟内存相关的地方。
