问题描述

我有大约1 milions项的字典。我不断循环扔dictionnary:

I have a dictionary with around 1 milions items. I am constantly looping throw the dictionnary :

    public void DoAllJobs()
    {
            foreach (KeyValuePair<uint, BusinessObject> p in _dictionnary)
            {
                if(p.Value.MustDoJob)
                    p.Value.DoJob();
            }
    }



执行是有点长,约600毫秒,我想deacrese它。这里是约束上:

The execution is a bit long, around 600 ms, I would like to deacrese it. Here is the contraints :


  1. MustDoJob值大多停留在同一beetween两次调用DoAllJobs()

  2. 的MustDoJob值==虚假

  3. 从时间到时间的60%-70%MustDoJob 200000双改变。

  4. 若干p.Value。 DoJob()不能在同一时间(COM对象调用)
  5. 在这里,我不需要_dictionnary的重要组成部分客体,但我真的需要在别的地方
  6. $ b来计算$ b
  1. MustDoJob values mostly stay the same beetween two calls to DoAllJobs()
  2. 60-70% of the MustDoJob values == false
  3. From time to times MustDoJob change for 200 000 pairs.
  4. Some p.Value.DoJob() can not be computed at the same time (COM object call)
  5. Here, I do not need the key part of the _dictionnary objet but I really do need it somewhere else

我要做到以下几点:


  • 并行,但我不知道将是有效的,由于4

  • 自排序1.和2. dictionnary(并停止想我找到的第一个MustDoJob ==假的),但我想知道什么3 。会导致

我没有实现任何以前的想法,因为它可能是很多工作,我想调查其他选项之前。所以...任何想法?

I did not implement any of the previous ideas since it could be a lot of job and I would like to investigate others options before. So...any ideas ?

推荐答案

我的建议是,你的业务对象可能引发一个事件来表明它需要做任务时 MustDoJob 为真,您可以订阅该事件,并引用存储在一个简单的列表中的那些对象,然后处理该列表中的内容时, DoAllJobs()方法被称为

What I would suggest is that your business object could raise an event to indicate that it needs to do a job when MustDoJob becomes true and you can subscribe to that event and store references to those objects in a simple list and then process the contents of that list when the DoAllJobs() method is called
