I couldn't find anything in the Debian patch to the source code, but the source code contains toolkit/components/contentprefs/src/nsContentPrefService.js 733-746: // Turn off disk synchronization checking to reduce disk churn and speed up // operations when prefs are changed rapidly (such as when a user repeatedly // changes the value of the browser zoom setting for a site). // // Note: this could cause database corruption if the OS crashes or machine // loses power before the data gets written to disk, but this is considered // a reasonable risk for the not-so-critical data stored in this database. // // If you really don't want to take this risk, however, just set the // toolkit.storage.synchronous pref to 1 (NORMAL synchronization) or 2 // (FULL synchronization), in which case mozStorageConnection::Initialize // will use that value, and we won't override it here. if (!this._prefSvc.prefHasUserValue("toolkit.storage.synchronous")) dbConnection.executeSimpleSQL("PRAGMA synchronous = OFF"); Probably they preferred the default value "off" so much that they even dropped the entry in standard configuration. > Do you see firefox pausing a lot under disk load? I see iceweasel pausing/blocking a lot when loading stalling webpages, but that's a different topic. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
