+Two S3 drivers are available. Historically, Arvados has used the @goamz@ driver to talk to S3-compatible services. More recently, support for the @aws-sdk-go-v2@ driver was added. This driver can be activated by setting the @UseAWSS3v2Driver@ flag to @true@.
+
+The @aws-sdk-go-v2@ does not support the old S3 v2 signing algorithm. This will not affect interacting with AWS S3, but it might be an issue when Keep is backed by a very old version of a third party S3-compatible service.
+
+The @aws-sdk-go-v2@ driver can improve read performance by 50-100% over the @goamz@ driver, but it has not had as much production use. See the "wiki":https://dev.arvados.org/projects/arvados/wiki/Keep_real_world_performance_numbers for details.
