Benchmark de Web Servers com SIEGE

  Benchmark de Web Servers com SIEGE
  ==================================

Colaboração: Danilo Egea Gondolfo

Software interessante, realiza teste de benchmark em servidores web. Ele
simula um número determinado de conexões por segundo durante um determinado
tempo em um web server. Testei no apache 2 em minha maquina FreeBSD 6.1
simulando 100 conexões por segundo durante 1 minuto, veja os resultados:


                comando -> siege -c100 -t1M localhost
                =====================================


  Lifting the server siege... done.
  Transactions: 11073 hits

Agora em duas instancias do Tomcat 5.5.17 com balanceamento de carga com apache 
2 :


                comando -> siege -c100 -t1M localhost/index.jsp
                ===============================================
