> RDBBlobStore uses a 64-char primary key (digest in hex).
> Unfortunately, this causes performance issues on MS SQL Server, when the
> collation for that column is of type "SQL*" (see links). These types of
> collations are deprecated, but still the default for installations on the
> "EN_US" locale.
> The performance loss can be observed by changing the collation on an existing
> install, and then enable performance logging on RDBBlobStore.
