+# FileShare Performance Tests
+
+In order to run the performance tests, the `azure-devtools` package must be installed. This is done as part of the `dev_requirements`.
+Start be creating a new virtual environment for your perf tests. This will need to be a Python 3 environment, preferably >=3.7.
+Note that tests for T1 and T2 SDKs cannot be run from the same environment, and will need to be setup separately.
+
+### Setup for test resources
+
+These tests will run against a pre-configured Storage account. The following environment variable will need to be set for the tests to access the live resources:
+```
+AZURE_STORAGE_CONNECTION_STRING=<live storage account connection string>
+```
+
+### Setup for T2 perf test runs
+
+```cmd
+(env) ~/azure-storage-file-share> pip install -r dev_requirements.txt
+(env) ~/azure-storage-file-share> pip install -e .
+```
+
+### Setup for T1 perf test runs
+
+```cmd
+(env) ~/azure-storage-file-share> pip install -r dev_requirements.txt
+(env) ~/azure-storage-file-share> pip install tests/perfstress_tests/T1_legacy_tests/t1_test_requirements.txt
+```
+
+## Test commands
+
+When `azure-devtools` is installed, you will have access to the `perfstress` command line tool, which will scan the current module for runable perf tests. Only a specific test can be run at a time (i.e. there is no "run all" feature).
+
+```cmd
+(env) ~/azure-storage-file-share> cd tests
+(env) ~/azure-storage-file-share/tests> perfstress
+```
+Using the `perfstress` command alone will list the available perf tests found. Note that the available tests discovered will vary depending on whether your environment is configured for the T1 or T2 SDK.
+
+### Common perf command line options
+These options are available for all perf tests:
+- `--duration=10` Number of seconds to run as many operations (the "run" function) as possible. Default is 10.
+- `--iterations=1` Number of test iterations to run. Default is 1.
+- `--parallel=1` Number of tests to run in parallel. Default is 1.
+- `--no-client-share` Whether each parallel test instance should share a single client, or use their own. Default is False (sharing).
+- `--warm-up=5` Number of seconds to spend warming up the connection before measuring begins. Default is 5.
+- `--sync` Whether to run the tests in sync or async. Default is False (async). This flag must be used for Storage legacy tests, which do not support async.
+- `--no-cleanup` Whether to keep newly created resources after test run. Default is False (resources will be deleted).
+
+### Common FileShare command line options
+The options are available for all SB perf tests:
+- `--size=100` Size in bytes of data to be transferred in upload or download tests. Default is 10240.
+- `--max-concurrency=1` Number of threads to concurrently upload/download a single operation using the SDK API parameter. Default is 1.
+- `--max-range-size`Maximum size of data uploading in single HTTP PUT. Default is 4*1024*1024.
+
+### T2 Tests
+The tests currently written for the T2 SDK:
+- `UploadTest` Uploads a stream of `size` bytes to a new File.
+- `UploadFromFileTest` Uploads a local file of `size` bytes to a new File.
+- `DownloadTest` Download a stream of `size` bytes. 
+- `DownloadToFileTest` Download `size` bytes into a local file.
+
+### T1 Tests
+The tests currently written for the T2 SDK:
+- `LegacyUploadTest` Uploads a stream of `size` bytes to a new File.
+- `LegacyUploadFromFileTest` Uploads a local file of `size` bytes to a new File.
+- `LegacyDownloadTest` Download a stream of `size` bytes. 
+- `LegacyDownloadToFileTest` Download `size` bytes into a local file.
+
+## Example command
+```cmd
+(env) ~/azure-storage-file-share/tests> perfstress UploadTest --parallel=2 --size=10240
+```
