Since then, we have updated to db4.4. If I recall correctly, there were concerns expressed by people about db4.5 (poor performance) and also db4.6 (possible performance issues, though I am not certain, and also lack of maturity). > Two things which should be considered: > > * I did not do any performance tests.

Now, I forget if that posting came from one of the group members or from someone who was just an interested user. However, with no perofmrance testing, I am reluctant to apply the patch. Unfurtonately, I am not capable to doing that testing myself either, since I do not personally use the db features of cyrus-sasl2. > * The data format between the various db4.x did not change, and > cyrus-sasl does not use on-disk transactions (in fact it does not > use any transactions at all, check grep -r DB_TXN).
