Try R# with VS in a solution with 54 projects and ~ 1.5MLOC...

It stinks!

Are you serious? That's a medium size project, just get a fast machine (e.g. i7 4770) and you'll be perfectly fine.

I've got an 8 core 3.0 Xeon with 32Gb RAM and Samsung 840. It's still slow.

It's more latency than long waits but it's enough to stop me using it.

8 core Xeon would be good at video rendering, but as of now for VS and R# you need single threaded performance, where a 3.9GHz Haswell shines.

Well, I don't know how many LOC I have, but I'm sure close to or more than that.

But we've got 62 projects. I've turned off a few things like code analysis in R# and it runs fairly well.

But the point is, we have to buy the costly VS AND pay a third party to get the real goodness of an IDE.
