rails,当渲染部分时,每个渲染输出在日志中.这是一个性能打击？

Question

例如,如果循环遍历@feed(呈现部分),则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 (1.5ms)
Rendered feeds/_feed_item.html.erb (1.6ms)

这是一个性能打击？有没有更好的方法来处理这个,所以它不会每次都输出？

谢谢

是的,这是一个性能打击.渲染一个集合.
