如何分析 Rails 中的缓慢动作？
我有一个动作花费大约 10 秒：
Completed 200 OK in 9489ms (Views: 1.3ms | ActiveRecord: 71.6ms)
我尝试用 benchmark 包装整个动作：
def action
self.class.benchmark("Processing projects") do
blahblahblah...
...
...
end
end
但它的报告看起来很奇怪：
how long does it take (692.2ms)
Completed 200 OK in 9489ms (Views: 1.3ms | ActiveRecord: 71.6ms)
我猜隐藏的 8.8s 是在某些 before_filter 或某物。但我怎样才能找到它呢？是否可以立即分析行动调用？
I have an action costs about 10s:
Completed 200 OK in 9489ms (Views: 1.3ms | ActiveRecord: 71.6ms)
I tried to wrap the whole action with benchmark:
def action
self.class.benchmark("Processing projects") do
blahblahblah...
...
...
end
end
But it's report looks strange:
how long does it take (692.2ms)
Completed 200 OK in 9489ms (Views: 1.3ms | ActiveRecord: 71.6ms)
I guess that the hidden 8.8s is in certain before_filter or something. But how could I find it? Is it possible to profile an action call at once?
