Testing the performance of a HelloWorld server does not mean many things but it does tell us where the ceiling is.
Below is the result using the command
http_load -p 10 -s 5 http://localhost:8080/ on my ThinkPad T400 laptop with ngx_openresty 22.214.171.124:
139620 fetches, 10 max parallel, 1.67544e+06 bytes, in 5.00001 seconds 12 mean bytes/connection 27923.9 fetches/sec, 335087 bytes/sec msecs/connect: 0.0531258 mean, 4.076 max, 0.014 min msecs/first-response: 0.258796 mean, 5.353 max, 0.067 min HTTP response codes: code 200 -- 139620
So on my laptop, for only a single worker nginx server, we've got ~28k r/s. The memory footprint of the
node process under load is 38.0m VIRT, 2.5m RES.
For comparison, HelloWorld servers using nginx + php-fpm 5.2.8 gives ~6k r/s:
http_load -p 10 -s 5 url 29703 fetches, 10 max parallel, 326733 bytes, in 5 seconds 11 mean bytes/connection 5940.6 fetches/sec, 65346.6 bytes/sec msecs/connect: 0.0394686 mean, 1.172 max, 0.02 min msecs/first-response: 1.62616 mean, 6.744 max, 0.719 min HTTP response codes: code 200 -- 29703
And node.js v0.6.1 yields 10k r/s:
51206 fetches, 10 max parallel, 614472 bytes, in 5 seconds 12 mean bytes/connection 10241.2 fetches/sec, 122894 bytes/sec msecs/connect: 0.0356567 mean, 1.316 max, 0.019 min msecs/first-response: 0.916395 mean, 14.236 max, 0.077 min HTTP response codes: code 200 -- 51206
The memory footprint of the
node process under load is 629m VIRT, 50m RES.
For Mac OS X Lion Users
Note that Mac OS X Lion has known issues that need to be fixed on your system before attempting to replicate our benchmark results.
In brief, raise the number of available ephemeral ports using this fix.
Compile an up-to-date version of ab (Apache's benchmark tool) according to this post.
ab -k -c10 -n10000 -t1 -r 'http://127.0.0.1:8080/' will deliver benchmark results.
Otherwise use an alternative lightweight HTTP load-testing tool weighttp and the invocation
weighttp -k -c10 -n10000 'http://127.0.0.1:8080/' for benchmarking.
