RabbitMQ memory test

Note: this repository only works on Windows.

It uses:

• Release 7.0.0-alpha.2
• Fork: branch prototype/reduce-memory-usage

How to run

1. Run RabbitMQ locally (e.g. using Docker) on port 5672 with the default user guest and password guest.
2. Clone this repository (git clone https://github.com/GerardSmit/RabbitMQ.MemoryTest.git)
3. Run the commands below.

Commands

You can run the test with dotnet run -c Release --. You can provide the following arguments:

Short	Long	Description	Default
-i	--iterations	The number of iterations to run.	required
	--mb	The size of the message in MB.	required
-t	--tasks	The number of tasks to run in parallel.	required
	--nc	Disable copying the message.	false
-q	--queue	The name of the queue to use.	test-queue

To use the fork, run the command with dotnet run -c Release -p:Fork=true --.

Examples

Run the test with 1 MB messages, 100 iterations and 16 tasks.

dotnet run -c Release -- --mb=1 --iterations=100 --tasks=16

Run the test with 1 MB messages, 100 iterations and 16 tasks, using the fork and disabling copying the message.

dotnet run -c Release -p:Fork=true -- --mb=1 --iterations=100 --tasks=16 --nc
