Saya memiliki situs web yang menggunakan https untuk mengirimkan file javascript ke klien. Situs webnya adalah getsimpleapps.com .
Ternyata file ini memuat 52 kali lebih lambat dengan https (20.08s - 29.08s) dengan http (380ms).
Beranda situs berbagi lambatnya sama dengan file javacript.
Saya baru-baru ini beralih dari dreamhost ke linode, dan meretas untuk mendapatkan SSL agar dapat bekerja di server baru hingga berhasil. Saya tidak melakukan konfigurasi gila.
Linode menjalankan Ubuntu 12.04 dan situs berada di atas tumpukan (LAMP).
Pertanyaan saya kepada komunitas stack overflow adalah: Bagaimana cara saya memperbaiki SSL & HTTPS di server saya? Saya tahu bahwa stack overflow dipenuhi dengan pertanyaan mengenai lambatnya HTTPS tetapi tidak ada solusi nyata yang diberikan. Tutorial atau panduan konfigurasi ubuntu akan ideal.
