Tambahan, kemungkinan memori juga berpengaruh.
Soalnya di kantor pakai komputer rakitan, memorinya 2 keping yg
tidak sama merek. Seringkali terjadi memori error, kalau beruntung
servernya masih bisa jalan kalo tidak ya stuck.
Sebaiknya komputer pakai yg branded jangan yg rakitan.
Dulu beli second IBM P-III/550MHz, 128MB, 10GB sekitar 500-600rb.
Lantas memorinya diupgrade ke 384MB, tambah HD baru 40GB.
Saya pakai itu untuk melayani servis (ini di kantor lain):
1. DNS server pakai djbdns
2. Proxy pakai safesquid+clamav antivirus
3. Webmail
4. IMAP
5. POP3
6. Postfix mailserver plus clamav (ndak kuat kalao pakai spamassasin)
7. Samba untuk file sharing
Pakai Redhat 9 dg kernel yg sdh dioptimasi.
