digitalmars.D.announce - vibe.d 0.7.14 and DUB 0.9.12 released

Apart from some fixes vibe.d received some performance tuning and
multi-threaded request processing (thanks to Dicebot for digging up some
documents of how Nginx does this). The result is a nice increase in
performance (~48 kreq/s vs. 25 kreq/s top) and >10k parallel connections
can now easily be handled, at least on 64-bit systems (the needed
_virtual_ memory can grow quite large, but real memory use stays low).

DUB has received a number of fixes for bugs that were introduced in the
previous release and some smaller enhancements. It now also has Debian
packages maintained by Jordi Sayol available.

Awesome! I had hoped you would add multi-threaded processing. I'm 
looking forward to playing with this.

How does it work? I added this to HttpServerSettings:
options |= HttpServerOption.distribute

But it doesn't seem to use more threads.

Combining that with 
http://vibed.org/api/vibe.core.core/enableWorkerThreads seems to 
do the trick for me (according to top output), but don't know if 
it is the supposed way.

Yes that's the correct way. To get full performance,
-version=VibeManualMemoryManagement is also needed, as every small bit
of GC usage has a big impact on performance (and due to the
stop-the-world nature it also has an even higher impact on
multi-threaded performance).

Just retested using weighttp instead of ab and now got up to 90 kreq/s
with "weighttp -c 100 -n 100000 -k http://127.0.0.1/empty".

Still way to go compared to what others claim (e.g. vert.x or gwan) but
since adding just some DB queries, file I/O or dynamic memory
allocations already destroy the numbers, this is really just a very
artificial setup for 99% of the applications anyway. Quite important for
marketing, though, I guess.

I have done a few performance tests and I am afraid I do not like 
where it gets. Not enough data for public review has been 
gathered yet, so I have sent my concerns via e-mail.

But to sum up short, feels like GC issues start to hit hard at 
higher concurrency levels.
