This metric varied between APIs and SDKs - the regression appears greater in Blobs (~20%) than FileShares (~10%).
Download speed for async operations in T2 is faster than sync operations in T1.

Cannot repro with v2.1.0 (using T1 perf tests: LegacyUploadTest/LegacyDownloadTest) and v12.1.0 (using T2 perf tests: UploadTest/DownloadTest). Results from testing sync locally:

Scenario Size Parallel 2.1.0 - time 2.1.0 - ops/s 12.1.0 - time 12.1.0 - ops/s
Upload 600 4 1000 ~26 1000 ~51
Download 600 4 1000 ~54 1000 ~54

Closing for now. Can re-open if issues come in and more investigation is needed.
