On a large file editing, moving very slowly, how can we increase the processing speed?

推荐答案

除了您实际上没有提供太多信息之外，有一个大文件".那是我不会去那里的主观价值.

首先，文件有多大?什么类型的文件?说这是一个有150,000条记录的平面文件.您可以放一个启动屏幕，然后将整个内容吸到内存中，然后以这种方式遍历.效率不高，但比直接处理平面文件要好.

您可以考虑吸收平面文件并将其加载到数据库中.这样可以加快处理速度，并使您的逻辑更容易.

可能是您刚刚编写了错误的代码.向我们展示您在做什么，您会得到更好的答案.

You really do not provide much information other than the fact you have a "large file". That is such a subjective value I won''t go there.

First, how large is the file? What type of file? Say it is a flat file with 150,000 records. You could put up a splash screen and suck the whole thing into memory then walk through it that way. Not efficient but better than processing a flat file directly.

You could consider sucking up the flat file and loading it into a database. That could speed up processing and make your logic easier.

It could be you have just written bad code. Show us what you are doing and you will get a better answer.
