Best SVN Benchmarks
Today you only have 2 options if you host your own server:
-
BDB (BerkeleyDB)
-
FSFS (Direct File System)
FSFS is the preferred backend these days and has been around for several years. There are almost no benefits to BDB and I think this is just for backward compatibility. FSFS is the default for any current SVN version. Many SVN binaries don't even have BDB support.

Please note that custom implementations are possible. For example, Google Code has its own SVN server based on their Bigtable architecture . Not sure if other SVN hosting providers are doing something similar.
In addition, the SVN developers are working on a replacement for FSFS called FSX or FS2 . However, it is still experimental.
