    8 core 2GHZ jauh lebih efektif + efisien, kalau 1 core 3GHz dikasih tugas banyak dikit udah tepar :D

    Tapi kayaknya opsi kedua bukan 8 x 2.0GHz, tapi 8 x 0.2 GHz.

    Kalau 1 x 3.0 GHz vs. 8 x 2.0 GHz sih mungkin mudah milihnya.. :)

    Benar .... pilihannya :
    8 x 0,2 GHz dan 1 x 3 GHz

    Sementara ini sih masih nampak seimbang .... he he he

    Pada kedua VPS tsb /etc/httpd/conf/httpd.conf sama-sama sbb :
    Code:
    Timeout 120
    KeepAlive On
    MaxKeepAliveRequests 100
    KeepAliveTimeout 3
    <IfModule prefork.c>
    StartServers       5
    MinSpareServers    5
    MaxSpareServers   25
    ServerLimit       50
    MaxClients        50
    MaxRequestsPerChild  5000
    </IfModule>
    
    Berarti kesimpulan adalah lebih cepat VPS 1 x 3 GHz ya ?
    Mohon pencerahannya.

    Terima kasih atas sharing nya .
