ttfb is too high

[isaccjr]

i'm trying to make a server to read the analogs e digital ports of the arduino. it all ready works, but the ttfb is too high. i'm getting 1,4 seconds per request and I don't know what to do to make it goes faster. I need less than 1s this 400 ms is really boring me up.

here is the code

undef PROGMEM

define PROGMEM attribute(( section(".progmem.data") ))

undef PSTR

define PSTR(s) (extension({static prog_char c[] PROGMEM = (s); &c[0];}))

Problem is not related to the WiFlyHQ library, general programming issue.
