We tried upgrading to 0.8.4, and while it was somewhat painless to upgrade, we were disappointed to see that compile times for our main app went up by 30%, from 22secs to 29secs, and that a basic non-scientific test
ab -n 100 -c 5 http:/localhost:8080/shows that our app is now only able to server 1.08 reqs/sec, down from 1.59 with 0.7.33.Note that our app uses vibe for much more than just serving the request. There are plenty of database and client HTTP request traffic.
We are going to stick to 0.7.3 for the time being :(
An interesting question would be to test this with subConfiguration "vibe-d:core" "libevent". In theory there shouldn't be a noticeable difference to 0.7.33 in that case.
Generally, the HTTP server is currently slower when using vibe-core, which is going to be fixed with the upcoming vibe-http package. The raw network code on the other hand should be faster than before.
But the request throughput generally seems awfully slow. Do you have an idea where the main CPU time is spent, or whether there may be some blocking I/O in the main thread?
