Upload benchmark examples
Basic upload benchmark:
azcopy bench "https://[account].blob.core.windows.net/[container]?[SAS]"High-throughput test (100 files × 2 GB each):
azcopy bench "https://[account].blob.core.windows.net/[container]?[SAS]" \
--file-count 100 --size-per-file 2G Test data is automatically deleted after the benchmark completes. Use --delete-test-data=false to preserve files.
