In this paper we propose to apply dynamic buffer tuning to make pervasive medical consultation successful. In pervasive consultation the physician can answer patient requests anytime, anywhere. The physician carries a SFF (small form factor) mobile device such as a mobile phone, which provides the interface to interact with the rest of the distributed Pervasive Digital HealthCare System (PDHD) on the mobile Internet. The PDHD in this paper caters to Traditional Chinese Medicine (TCM) and therefore called TCM-PDHD or simply T-PDHD. The T-PDHD usability relies on various factors such as: a) correct information transfer, and b) fast system response. This paper focuses on the second factor and explores how the dynamic buffer tuning technique can be exploited to quicken system response.
