ruby-on-rails - Rails，渲染部分时，每个渲染都会在日志中输出。这是性能打击吗？

Question

例如，如果循环@feed(呈现部分内容)，您会在日志中看到以下内容:

Rendered feeds/_feed_item.html.erb (2.5ms)
Rendered feeds/_feed_item.html.erb (1.4ms)
Rendered feeds/_feed_item.html.erb (1.3ms)
Rendered feeds/_feed_item.html.erb (1.3ms)
Rendered feeds/_feed_item.html.erb (1.4ms)
Rendered feeds/_feed_item.html.erb (1.3ms)
Rendered feeds/_feed_item.html.erb (1.3ms)
Rendered feeds/_feed_item.html.erb (1.5ms)

Rendered feeds/_feed_item.html.erb (1.4ms)
Rendered feeds/_feed_item.html.erb (1.5ms)
Rendered feeds/_feed_item.html.erb (1.6ms)

这对性能有影响吗？有没有更好的方法来处理这个问题，这样它就不会每次都输出？

谢谢

是的，这对性能造成了影响。渲染集合。
