    W3 Total Cache rallenta il sito a causa del .htaccess!

    Ciao a tutti,

    ho notato che da quando ho installato W3 Total Cache sul mio sito mtlook.it c'è stato un rallentamento drastico nell'inizio di caricamento pagina. Se è vero, com'è vero, che i punteggi Google Speed e GTMetrix sono aumentati di molto (probabilmente non calcolano il tempo di risposta del sito), è anche vero che dal punto di vista utente la situazione è peggiorata.

    Badate bene che non è il tempo di caricamento ad essere aumentato, ma il tempo che intercorre tra la digitazione del sito e l'inizio del caricamento.

    Col tempo ho scoperto che tale problema è dovuto all'enorme file .htaccess che va a generare il plugin (che vi riporto di seguito).

    Il fatto è che se cancello tutta la parte W3TC il tempo di risposta finalmente scende vertiginosamente, ma i punteggi di Google Speed e GTMetrix calano drasticamente.

    Come devo fare? Mi date una mano a risolvere questa cosa? Grazie mille!

    Ciao iGianni84, W3TC ha molti settaggi di configurazione, non è un plugin semplice, servirebbe una url (senza www e non attiva) del sito per poterti consigliare quali impostazioni usare.
