If I remember correctly, Arc is an ongoing experiment in language design, not high-performance implementation.
And it's running on top of PLT Scheme, which adds another layer of interpretation.
And it's running as a single process on a single server without a database storing everything on the file system. That it's doing the traffic it is I find quite impressive.
In 2 GB of memory.

Are there any articles on the "HN storing everything on the file system"?
I am quite interested in the architecture, because I found this approach nice for some sites I was building. They were not very large though.

> without a database
Why?
I can understand not using a database if this was improving the performance.
PLT Scheme is not "interpreting" code. More than that, Arc adds a bunch of huge overheads that could make things substantially faster. I had some patches lying around that made things around 4-5 times faster (including the news server).
but it's calling all those ar_funcall2 or whatever ... not that much indirection really.
