Benchmarks

    I used 4 VMs for the tests with the following configuration:

    • 32 GB RAM
    • 8 CPU Cores
    • 10 GB SSD
    • Ubuntu 14.04 LTS 64-bit
    • One VM used to launch the benchmarking tool wrk
    • One VM for traefik (v1.0.0-beta.416) / nginx (v1.4.6)
    • Two VMs for 2 backend servers in go
      Each VM has been tuned using the following limits:
    1. user www-data;
    2. worker_processes auto;
    3. worker_rlimit_nofile 200000;
    4. pid /var/run/nginx.pid;
    6. events {
    7.     worker_connections 10000;
    8.     use epoll;
    9.     multi_accept on;
    10. }
    12. http {
    13.     sendfile on;
    14.     tcp_nopush on;
    15.     keepalive_timeout 300;
    16.     keepalive_requests 10000;
    17.     types_hash_max_size 2048;
    19.     open_file_cache max=200000 inactive=300s;
    20.     open_file_cache_valid 300s;
    21.     open_file_cache_min_uses 2;
    22.     open_file_cache_errors on;
    24.     server_tokens off;
    27.     include /etc/nginx/mime.types;
    28.     default_type application/octet-stream;
    30.     access_log /var/log/nginx/access.log combined;
    31.     error_log /var/log/nginx/error.log warn;
    33.     gzip off;
    34.     gzip_vary off;
    36.     include /etc/nginx/conf.d/*.conf;
    37.     include /etc/nginx/sites-enabled/*.conf;
    38. }

    Here is the Nginx vhost file used:

    1. MaxIdleConnsPerHost = 100000
    2. defaultEntryPoints = ["http"]
    4. [entryPoints]
    5.   [entryPoints.http]
    6.   address = ":8000"
    7. [file]
    8. [backends]
    9.   [backends.backend1]
    10.     [backends.backend1.servers.server1]
    12.     weight = 1
    13.     [backends.backend1.servers.server2]
    14.     url = "http://IP-whoami2:80"
    15.     weight = 1
    17. [frontends]
    18.   [frontends.frontend1]
    19.   backend = "backend1"
    20.     [frontends.frontend1.routes.test_1]
    21.     rule = "Host: test.traefik"
    1. wrk -t20 -c1000 -d60s -H "Host: test.traefik" --latency  http://IP-nginx:8001/bench
    2. Running 1m test @ http://IP-nginx:8001/bench
    3.   20 threads and 1000 connections
    4.   Thread Stats   Avg      Stdev     Max   +/- Stdev
    5.     Latency   101.25ms  180.09ms   1.99s    89.34%
    6.     Req/Sec     1.69k   567.69     9.39k    72.62%
    7.   Latency Distribution
    8.      50%   15.46ms
    9.      75%  129.11ms
    10.      90%  302.44ms
    11.      99%  846.59ms
    12.   2018427 requests in 1.00m, 298.36MB read
    13.   Socket errors: connect 0, read 0, write 0, timeout 90
    14. Requests/sec:  33591.67
    15. Transfer/sec:      4.97MB

    Traefik is obviously slower than Nginx, but not so much: Traefik can serve 28392 requests/sec and Nginx 33591 requests/sec which gives a ratio of 85%. Not bad for young project :) !

    • Run a separate server instance per CPU core with (it appears during benchmarks that there is a lot more context switches with traefik than with nginx)
