My recommendations for the autoCommit settings are on that URL that I linked - maxTime set to five minutes with openSearcher set to false. It also has a maxDocs setting ... you would need to come up with a reasonable setting for that, or just leave it out. That takes care of all hard commit requirements as they relate to the transaction log. Aside from that, I would recommend using soft commits (either explicit or autoSoftCommit) for document visibility. Hard commits with opensearcher=true work fine, but soft commits have a *little* bit less impact. It would be up to you to decide when and how often to do that, but I wouldn't do it more frequently than once a minute unless you can take steps to make those soft commits happen REALLY fast. Making commits happen faster is a separate discussion.
