Benchmarks

A playground for experimenting with different server models.

Environment

We're using the following physical machines to perform these tests:

Name	OS	Role	CPU	RAM	NIC
perfsvr	Windows Server 2012 R2	Web Server	Xeon E5-1650	32 GB	Intel® Ethernet Converged Network Adapter X540-T1 10GbE
perfsvr2	Ubuntu 14.04 LTS	Web Server & Load Generator	Xeon E5-1620	32 GB	Intel® Ethernet Converged Network Adapter X540-T1 10GbE
perf02	Windows Server 2012 R2	Load Generator	Xeon W3550	24 GB	Broadcom NetXtreme Gigabit Ethernet (BCM5764)
perf03	Ubuntu 14.04 LTS	Load Generator	Xeon W3550	12 GB	Intel® Ethernet Converged Network Adapter X540-T1 10GbE

The machines are connected to an 8-port Netgear XS708E 10-Gigabit switch.

Load Generation

We're using wrk to generate load from one of our Linux boxes (usually perfsvr2). We also have WCAT) set up on perf02 but it as it doesn't support HTTP pipelining we've stopped using it for now.

Results

For each stack, variations of the load parameters and multiple runs are tested and the highest result is recorded.

Plain Text

Similar to the plain text benchmark in the TechEmpower tests. Intended to highlight the HTTP efficiency of the server & stack. Implementations are free to cache aggressively and remove/disable components that aren't required in order to maximize performance.

Stack	Server	Req/sec	Load Params	Impl	Observations
ASP.NET 4.6	perfsvr	65,383	8 threads, 512 connections	Generic reusable handler, unused IIS modules removed	CPU is 100%, almost exclusively in user mode
IIS Static File (kernel cached)	perfsvr	276,727	8 threads, 512 connections	hello.html containing "HelloWorld"	CPU is 36%, almost exclusively in kernel mode
IIS Static File (non-kernel cached)	perfsvr	231,609	8 threads, 512 connections	hello.html containing "HelloWorld"	CPU is 100%, almost exclusively in user mode
ASP.NET 5 on WebListener (kernel cached)	perfsvr	264,117	8 threads, 512 connections	Just app.Run()	CPU is 36%, almost exclusively in kernel mode
ASP.NET 5 on WebListener (non-kernel cached)	perfsvr	107,315	8 threads, 512 connections	Just app.Run()	CPU is 100%, mostly in user mode
ASP.NET 5 on IIS (Helios) (non-kernel cached)	perfsvr	109,560	8 threads, 512 connections	Just app.Run()	CPU is 100%, mostly in user mode
NodeJS	perfsvr	96,558	8 threads, 1024 connections	The actual TechEmpower NodeJS app	CPU is 100%, almost exclusively in user mode
Scala	perfsvr	204,009	8 threads, 1024 connections	The actual TechEmpower Scala plain text app	CPU is 68%, mostly in kernel mode
libuv C#	perfsvr	300,507	12 threads, 1024 connections	Simple TCP server, not real HTTP yet, load spread across 12 ports (port/thread/CPU)	CPU is 54%, mostly in kernel mode

Plain Text with HTTP Pipelining

Like the Plain Text scenario above but with HTTP pipelining enabled. Only stacks/servers that support pipelining are included.

Stack	Server	Req/sec	Load Params	Impl	Observations
NodeJS	perfsvr	148,934	8 threads, 1024 connections	The actual TechEmpower NodeJS app	CPU is 100%, almost exclusively in user mode
Scala	perfsvr	764,775	8 threads, 1024 connections, pipelining 15 deep	The actual TechEmpower Scala plain text app	CPU is 46%, mostly in kernel mode, 1Gbps NIC saturated (need to re-run on 10GbE)
libuv C#	perfsvr	2,379,267	36 threads, 288 connections, pipelining 15 deep	Simple TCP server, not real HTTP yet, load spread across 12 ports (port/thread/CPU)	CPU is 100%, mostly in user mode, gets slower as test runs longer, issue somewhere

Plain Text with HTTP 2
