Capacity and reliability

I work in the configuration management department of a good sized financial institution in the Chicago area.  The company is in the process of converting all of its version control operations to Subversion.  As part of an internal audit, we are being asked for evidence that Subversion has the capacity to support our operations.

I'm guessing that there is very little 'hard' evidence available, and that most of it will be anecdotal.  Any information that you could provide will be helpful.

We are more interested in other's experiences, than a critique of our configuration.  That said, below is a brief description of our environment.

- Our svn server runs on a dedicated Linux box with dual 3.2 GHz processors, 4GB of RAM, and 100 GB of NAS disk
- It is configured using FSFS
- Initial repository size is approximately 250MB.  We expect the repository to grow by about 50MB per day.
- We anticipate around 100 server accesses (checkout, checkin, status, etc.) per hour and around 1000/day.

Here are some of my questions:

- How large is your repository in terms of total commits and disk space?
- Are you using Berkeley DB of FSFS?
- What sort of hardware are you running?  Which OS? Processing capacity? How much RAM?
- What is your transaction volume like? Average number of concurrent transactions? Number if commits per day?
- Have you had any serious issues and/or what issues do you have maintaining your repository?
- How long has your repository been in existence?

By the way, survey information like this would be a great thing to have on the Subversion web site.  Especially for corporate users that are looking to replace commercial products.  I'd be happy to contribute our statistics from time-to-time.

Best regards,
