[p2-dev] Use of uncompressed metadata repositories

Hi folks,

I am trying go get a feel for how widely used uncompressed metadata repositories are.

A typical content.xml file contains many copies of identical license text.  Memory use is not an issue since the implementation uses a StringPool to extern string references.  Compressed repositories do not present an issue for disk foot print or network traffic as the content.xml compresses extremely well, typically 95% or more.

However, uncompressed metadata repositories may pose a significant concern here if they are widely used.

So does anybody have an opinion on how widely used uncompressed repositories are?
