>          Components: fs/s3
>    Affects Versions: 2.8.0

> The ITestS3AInputStreamPerformance.testTimeToOpenAndReadWholeFileBlocks takes 15s on
branch-2, but is now taking minutes on branch-2.8.
> This is a regression, and it's surfacing on some internal branches too. Even where the
code hasn't changed. It does not happen on branch-2, which has a later SDK.
