Initial scan and page loads are slow on Subversion
When you add a repository, Fisheye needs to perform a once-off scan through the repository to build up its initial index and cache. This scan can take some time. Until this scan is complete, you may find that some data is not displayed. As a guide, Fisheye should be able to process about 100KB-200KB per second on an averaged-size PC. If Fisheye is accessing the repository over the network (e.g. over a NFS mount), then you should expect the initial scan to take longer. Read on if your scan appears to be considerably slower than expected.
It's possible that you've mis-configured your tag and branch structure and caused Fisheye to process some or all files as trunk files. You should recheck your tag configuration.
If that fails, then the Atlassian support team will be happy to help you with this issue. Please sign up for a support account if you don't have one already, then login and create a Fisheye support request.
Users with very large or non-local repositories may be able to improve their Fisheye scan performance.
