Eeek! That will be incredibly slow over any kind of network other than fast gigabit! try doing a ping from the client to the server. If it over the internet you will be lucky to get less that 100ms, over a fast LAN it might be around 30ms. Add in the transmission time for your data - (ie 150*ave string length*10/average bandwidth) That network delay will swamp any optimisation of a for loop. It is likely to come out around 10ms so your total delay between each character becomes 40-110ms or a maximum typing rate of 9-25 characters per second. The latter will feel slightly clunky but the former will feel very sluggish. And on anything less than a good internet connection the rate could drop off to around 1 character per second! And anyone using a mobile GPRS connection for access would be crippled.
