View Source BeamBenchmarks
This is a collection of Erlang benchmarks copied from other projects for ease of use. This project makes these benchmarks a hex dependency and helper function away. Some documentation is copied here for convenience, but please see the source projects for more complete information.
Benchmarks include:
Name | Source | Description |
---|---|---|
bang | bencherl | A benchmark for many-to-one message passing that spawns one receiver and multiple senders that flood the receiver with messages. |
big | bencherl | A benchmark that implements a many-to-many message passing scenario. |
binary_trees | benchmarksgame | Allocate and deallocate many many binary trees |
chameneos_redux | benchmarksgame | Symmetrical thread rendezvous requests |
ehb | bencherl | This is an implementation of hackbench in Erlang, a benchmark and stress test for Linux schedulers. |
estone | estone_SUITE.erl | This is a suite of benchmarks that measure performance of various Erlang primitives. |
ets_test | bencherl | This benchmark creates an ETS table and spawns several readers and writers that perform a certain number of reads (lookups) and writes (inserts), respectively, to that table. |
fannkuch_redux | benchmarksgame | Flipping pancakes |
fasta | benchmarksgame | Generate and write random DNA sequences |
genstress | bencherl | This is a generic server benchmark that spawns an echo server and a number of clients. |
k_nucleotide | benchmarksgame | Hashtable update and k-nucleotide strings |
mandelbrot | benchmarksgame | Generate Mandelbrot set portable bitmap file |
mbrot | bencherl | This benchmark extrapolates the coordinates of a 2-D complex plane that correspond to the pixels of a 2-D image of a specific resolution. |
nbody | benchmarksgame | Model the orbits of Jovian planets using a simple symplectic-integrator |
orbit_int | bencherl | This benchmark operates on a distributed hash table, and follows a master/worker architecture. |
parallel | bencherl | A benchmark for parallel execution that spawns a number of processes, each of which creates a list of $N$ timestamps and, after it checks that each element of the list is strictly greater than its previous one (as promised by the implementation of erlang:now/0), it sends the result to its parent. |
pcmark | bencherl | This benchmark is also about ETS operations. It creates five ETS tables, fills them with values, and then spawns a certain number of processes that read the contents of those tables and update them. As soon as one process finishes, a new process is spawned, until a certain total number of processes has been reached. The benchmark is parameterized by the number of initial processes and the total number of processes. |
pidigits | benchmarksgame | Streaming arbitrary-precision arithmetic |
ran | bencherl | Another benchmark for parallel execution that spawns a certain number of processes, each of which generates a list of ten thousand random integers, sorts it and sends its first half to the parent process. The benchmark receives the number of processes as a parameter. |
regex_redux | benchmarksgame | Match DNA 8-mers and substitute magic patterns |
reverse_complement | benchmarksgame | Read DNA sequences - write their reverse-complement |
serialmsg | bencherl | A benchmark about message proxying through a dispatcher. The benchmark spawns a certain number of receivers, one dispatcher, and a certain number of generators. The dispatcher forwards the messages that it receives from generators to the appropriate receiver. Each generator sends a number of messages to a specific receiver. |
spectral_norm | benchmarksgame | The "Hundred-Dollar, Hundred-Digit Challenge Problem" |
thread_ring | benchmarksgame | Switch from thread to thread passing one token |
timer_wheel | bencherl | A timer management benchmark that spawns a certain number of processes that exchange ping and pong messages. |

All other benchmarks have a similar API that runs the one test and returns the
result, timing, and other info in a BeamBenchmarks.Results.t/0
struct. These
run pretty quickly with default settings, but become much more interesting load
generates when passed bigger arguments.
