    203203You should choose meaningful time interval and timeout settings: the more resources are to be synchronized, the longer it will take (in this regard, also note that THIS- and OTHER-policies will always exchange all records in a resource, thus taking significantly longer).
    204204
    205 How many record have to be exchanged per each run depends on the average update frequency and the time internal between synchronizations: e.g. if there are on average 100 record updates per minute, and you set a 2-minute interval, then there would be 200 records on average to be transmitted every run. The import rate on a small server has been tested at on average 18 records/second, which means, the synchronization process would take around 11 seconds in this case. To be on the safe side, choose a timeout value at least 10 times as high as that - e.g. 120 seconds.

    207207Note that the network traffic arising from synchronization does not mainly depend on the frequency of synchronization, but on the record update rate at the sites. Smaller synchronization intervals would increase the traffic only slightly, but reduce the rate of conflicts and the risk of network-related problems. However, too small intervals (below the update rate of the site) may cause unnecessary network traffic with just empty transmissions.
