progressbars [英] progressbars

问题描述

我有一个非常耗费处理器的方法，我想报告它的
进度。当我让它更新进度条，标签，打印到控制台

等时，它会大大减慢方法。


有没有办法避免这种情况？


谢谢

我想你在一个辅助线程上运行它，对吗？你经常用什么来b $ b更新进度条？

当它发生时对性能有一些影响是很正常的

太频繁了。

我想你是在一个辅助线程上运行的，对吧？，你多久一次更新进度条？

不，我不运行它一个辅助线程。这会增加

性能如何更新prgbar？

谢谢

不，它不会，但它会保持UI响应。每当你打断你的

处理器绑定时更新UI的代码路径它会损害你的b / b
性能，除非你在多核或HT CPU上运行它。

Hi,
I have a very processor intensive method, and I want to report its
progress. When i get it to update a progressbar, label, print to console
etc. it vastly slows the method down.

Is there a way to avoid this?

Thanks

Andrew

I suppose you run this on an auxiliary thread, right?, How often do you
update the progress bar?
It''s quite normal that this has some impact on performance when it happens
too often.

Hi, no I dont run it on an aux thread. Would doing this increase
performance wrt updating a prgbar?
Thanks

No, it won''t, but it keeps the UI responsive. Whenever you interrupt your
"processor bound" code path to update the UI it''s gonna hurt your
performance, unless you run this on a multi-core or HT CPU.
