Wow, 400-500ms pauses? Is that the case in newer Go versions as well? Seems like...

Go is actively working on this. Go 1.5 will have concurrent GC and is shooting to stop the world for only 10ms. You can read more here: https://docs.google.com/document/d/16Y4IsnNRCN43Mx0NZc5YXZLo...

Not really. If you manage your allocations properly, you will never have such long GC pauses.

N.B. we use Go for real-time bidding (in the context of programmatic buying of ad space), and can easily respond to 6000 QPS on a single server within a 100ms time frame (from the SSP's POV), with a working set of about 2-3 GB that we constantly keep in memory.

Like the author's case, yours sound a much more appropriate choice of Java. Why have you picked Go?

Probably hype. There is a lot of hype in the industry, unfortunately.

That sounds really nice, but how often does that working set change?
