[TingDaoK]

Issue #, if available:

• Some customer saw the error from the first byte timeout being too restrict and lead to fail the retries.

Description of changes:

• Update the first byte timeout to be more reasonable.

Current main benchmark 1x30GiB file upload with c5n.18xlarge:

With this change same workload:

Overall there is no performance downgrade from this change on the benchmark.

Meanwhile, if I just disable the timeout, the same workload result in:

there is an around 22% performance downgrade.
