Otimizar codigo Arduino

Olá galera.

Estou criando um projeto de automação residêncial, com ethenet shield v1.1, com poucas lampadas ele funciona mas a medida que aumento o tamanho do código ele carrega mas nao abre e depois da falha.

Alguém sabe um modo de otimizar esse código?

#include "etherShield.h"
#include "ETHER_28J60.h"

int PinoLed7 = 7;
int PinoLed6 = 6;

static uint8_t ip[4] = {10,0,0,7};  

static uint16_t port = 80;
