Speaking for myself, I think writing and using buckets with serf is more straightforward than our complicated bucket brigade system with mixed push/pull paradigms.

It very well may be.

Async may be easy. Except when my db connection blocks.. On stat calls.. Etc.

I am by no means defending the buckets! Or anything for that matter... Just some observations. I just no longer buy into the idea that async is somehow inherently superior. It sounds good in theory, but in the "real world" I am just not seeing it.

The whole reason I brought this up was to stimulate discussion. I really really would hate for us to spend many months porting everything over to async to discover that it made no positive impact on performance. Worse, it made extending httpd (or "D") much harder.
