Interesting paper from CERN comparing ZeroC to other middleware systems

Hard to tell if they are really comparing apples to apples, they don't really explain their method....

I think it compares apples to apples, but as you mention, the method to me is a bit iffy.
For example, they're giving a 6 to ZeroMQ and 5 to Ice because of use of resources, but the thing is, as they mentioned earlier in the paper, for ZeroMQ you need to create your own serializer, in contrast to Ice that has everything you need.
So pretty much, I think that having to roll out in-house your own serializer is a big turn off, as implementing such a feature is really hard and cumbersome to do, specially if it has to work on multiple platforms, and Ice's marshaller has years of field test and you know that works, and works amazing, so If in the end, you actually do serialization instead of using ZeroMQ raw like they did, then I'm sure Ice would win hands down.
