I have an extremely large Subversion repository being indexed in FishEye. It's a few million lines of almost 20 year old code that is heavily branched. Since SVN branching doesn't do client-side diffs, rather they're full copies (at least for our version), it means the FishEye index is huge (~10GB) for this repository.
To make things wose, our FishEye instance is running on a virtualised platform with particularly slow disk I/O, so loading up a file that's been edited a bit over the years can take 10 minutes in some cases.
I've just read the diff info documentation and am now wondering if disabling diff info will help speed up this repository.
In what cases will the repository be faster? What sacrifices will we be making if I switch it over? e.g. can we still load up HEAD code quickly, even for branches? will we suffer worse performance (since it's a remote SVN over HTTPS server) on anything in particular?
When you disable diff info FishEye will no longer index or store diffs. This will have a couple of benefits:
But you will lose the ability to do diff searches (search for revisions in which a particular line of code was added/removed). You will still be able to do full-text (content) search on the HEAD code.
Disabling diff info should not directly impact the performance of visiting the file history page, or getting the file content of a file. You may get some indirect performance benefits, but it's hard to tell whether they will be significant:
Hope this helps.
