Re: [cross-project-issues-dev] Eclipse SDK I build mirrors?

[Denis Roy <denis.roy@xxxxxxxxxxx>]

Kim is right - we had a noticeable bandwidth *decrease* when we applied 
the Nightly/I-build filter for the mirrors - especially during weeks 
where Platform (or any other project) runs builds back-to-back.

It depends to whom. The IBM and a few other internal mirrors get the 
complete dataset. I assume they are the largest consumers of N and I 
builds, so we're saving bandwidth there.  I also assme that when an 
individual consumes a nightly build, they're not downloading the entire 
2.6GB dataset, but only a fraction of it -- therefore, many, many 
downloads need to occur before mirroring 2.6GB to X mirrors becomes 
profitable.
