Re: loop speed

The Arduino is not the fastest device in the world nor is the Ethernet shield spritely. I think you're doing well to get the loop to execute successfully once per second.

If the table you are using is a lookup table and thus data does not change frequently, you should move the query to startup() and store the values in memory.

OTOH, you should write your code to refresh the data as often as you expect it to change. In other words, how often does the value in the table differ? Is it really once per second?
