Tests the upload speed to Azure blob storage. This takes a URL to a blob container with a SAS in parameter, then tests speed for:

• uploading one file as a block,
• one file in parallel chunks,
• several files and in parallel.

Install

npm install -g azspeedtest

Usage

Pre-requisite: Generate a shared access signature for a blob container. The SAS must have write and delete access to the container. Create a container for that purpose. It will look like: https://myaccount.blob.core.windows.net/speed-test?st=2018-04-09T12%3A49%3A00Z&se=2018-05-10T12%3A49%3A00Z&sp=rwdl&sv=2017-04-17&sr=c&sig=%2BnH4OrCflkgdldiqjZcLCvHZAFbR19ISrTGLk1oVmPQ%3D`.

azspeedtest --url="<URL WITH SAS>" --size=10 --chunks=5

#### OUTPUTS:
# Upload one 10MB file as a block: 1.52 Mb/s...
# Upload one 10MB file in 5 chunks: 1.54 Mb/s...
# Upload 5 x 2MB files in parallel: 1.48 Mb/s...
# Done                           .

The command also writes a result file in the container.

Options:

• url specifies the URL with SAS to the container
• size specifies the upload size in MB. Defaults to 10MB.
• chunks specifies the decomposition level in chunks. I.e. it will upload the file in x chunks, and x files in parallel. Defaults to 4.
• no-cleanup prevents cleanup at the end of the test
