There are multiple factors at work here, The primary one being that by design, unless you are writing to an array, the server writes one item at a time. It has been that way since v2,7 of the server. Unfortunately intouch does not support arrays, unless that has changed. This means that the write will be placed in a write queue until they can be processed. This queue can be monitored using the _Statistic._Pending writes tag which should be able to be read by any client. For WW you many need to play around with Topic.
