puts.. to achando estranho isso.. hoje, ultilizei o cachemgr.cgi para dar
uma olhada
no final deste relatorio tem a seguinte informacao
TOTALS
ICP : 0 Queries, 0 Hits ( 0%)
HTTP: 93443 Requests, 37037 Hits ( 40%)

esta dizendo 40% de HITS..
estou interpretando errado ?????

Olha pelo que esta escrito ai, o seu cache não tem cache .... :)
Nos ultimos 5min teve mais erro no cache (misses 0,46965)) to que
acertos (Hits). Posso estar falando besteira, mas se isso é em
percentual (46,96%) ele ta muito ruim pois os acertos são 1,23 %
Verifique a quantidade de memopria que ele utiliza, quanto mais
cache em memoria melhor, tempo de expiracao do cache na memoria e
em disco
