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:
urlspecifies the URL with SAS to the containersizespecifies the upload size in MB. Defaults to 10MB.chunksspecifies the decomposition level in chunks. I.e. it will upload the file in x chunks, and x files in parallel. Defaults to 4.no-cleanupprevents cleanup at the end of the test
