| Subject: | Nethttpd_plex performance question |
Hello
I'm trying to write a simple webserver using Nethttpd_plex from the
ocamlnet package. I did a simple benchmark using the examples provided
in the distribution (easy_daemon.ml and netplex.ml). Both examples
create static pages, but the netplex version shows worse performance,
which I think is odd because it uses a multi-process model, while
easy_damon is a single process handling all requests.
I'm running "ab" (apache's benchmark tool), doing 1,000 connections, 100
concurrently. Here are the results:
- easy_daemon:
Requests per second: 1699.87 [#/sec] (mean)
- netplex:
Requests per second: 591.22 [#/sec] (mean)
[netplex's results actually vary a lot, sometimes reaching about 1,000
req/s but sometimes also being as low as 300 req/s. On average it seems
to be around 600 req/s]
I'm using the following configuration for netplex's workload_manager:
workload_manager {
type = "dynamic";
max_jobs_per_thread = 1;
min_free_jobs_capacity = 30;
max_free_jobs_capacity = 50;
max_threads = 256;
};
Also, even though I'm using Netplex_mp.mp (multiple processes, instead of
multiple threads), compiling with -thread gives me a performance gain
(the numbers above are for a compilation with the -thread flag). Is that
expected?
Does anyone have any tips for improving netplex's performance? I believe
that with the right settings it should be able to outperform the simpler
daemon easily, since it's using multiple processes.
Thanks in advance,
Andre
