What? Compression is absolutely essential throughout computing as a whole, especially as CPUs have gotten faster. If you have compressible data sent over the network (or even on disk / in RAM) there's a good chance you should be compressing it. Faster links have not undercut this reality in any significant way.
Whether or not to compress data before transfer is VERY situationally dependent. I have seen it go both ways and the real-world results do not not always match intuition. At the end of the day, if you care about performance, you still have to do proper testing.
(This is the same spiel I give whenever someone says swap on Linux is or is not always beneficial.)
