Este teste faz parte de um conjunto de testes, completamente legais que efectuámos via link, para determinar a performance do site.
Não iremos testar o nível de segurança, visto que isso já poderia ser considerado do ambito da ilegalidade.
E nós não entramos em elegalidades...
Um site tão caro com umas métricas tão baixas, é caso para perguntar; Que manutenção é essa?
Nos tempos que correm com o país na miséria, é efectuado um contracto de manutenção de um site em Joomla, por 73.554,00 Euros... com cortes em ordenados e subsidios de Natal e Férias!
Isto é INADMÍSSIVEL, mesmo sem ser em tempo de crise.
Importa referir que o contracto com a duração de 365 dias (1 ano), foi celebrado em 19-09-2011, e que decorrido todo este tempo, o site o site apresenta as características abaixo
