最快的c ++文件压缩库可用？ [英] fastest c++ file compression library available?

问题描述

我需要找到最好的库来压缩内存数据。
我目前使用zlib，但我想知道是否有一个更好的压缩库;更好的性能和内存占用。

I have a need to find the best library to compress in memory data. I am currently using zlib but I am wondering if there is a better compression library; better in terms of performance and memory footprint.

它应该能够处理同一存档中的多个文件。

It should be able to handle multiple files in the same archive.

我正在寻找一个C / C ++库。

I am looking for a C/C++ library.

性能是关键因素。正在压缩的文件是小到大的XML文件。

Performance is the key factor. The files that are being compressed are small to large XML files.

推荐答案

大多数lib都有一个C API而不是C ++。你可以看看lzo，这是相当快，但在压缩率方面不是很好。

Most libs have a C API rather than C++. You can look at lzo, which is fairly fast but not as good in terms of compression ratio.

More details about lzo (from its website, thanks Chris for correcting the link)

• 无需解压缩内存


• 压缩速度非常快。


• 需要64 KB的压缩内存。

请注意，lzo可以处理内存缓冲区，因此您必须自己处理文件的转换。

Note that lzo works on memory buffers, so you'll have to handle the conversion to/from files yourself.

lzo是GPL，这可能是一个问题，这取决于您的应用程序。

Also note that lzo is GPL which may be a problem, depending on your application.
