texte = On my side, i found that "Commit Databases Automatically After Modification" was too heavy for large DB with lot of activity: i unchecked it, which made my system faster, and i use a [FLUSHDATABASES] tag in pages i know will be regularely loaded, but not as often as when a database is modified. In both cases, i think that databases are ALL flushed. If the server is rebooted, WebDNA flushes the databases before shutting down. If the server crashes, your last modifications will be lost, yes. It is a matter to compare speed with security. chris On Apr 13, 2008, at 16:06, Tennis De Jong wrote: > I have not seen a pattern.
