8 core 2GHZ jauh lebih efektif + efisien, kalau 1 core 3GHz dikasih tugas banyak dikit udah tepar :D
 
Benar .... pilihannya :
8 x 0,2 GHz dan 1 x 3 GHz

Sementara ini sih masih nampak seimbang .... he he he
 
Benar2 kelihatan beda.

Sesuai dengan referensi dari http://www.cyberciti.biz/tips/howto-performance-benchmarks-a-web-server.html saya coba test dan didapatkan hasil sbb :

VPS dengan CPU = 1 x 3,0GHz (alias = aaaa)

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 .
