Mungkin bisa diperiksa dulu si di telusurin dulu. karena pastinya perlu optimasi. kalau untuk mengurangi proses tersebut bisa pakai layanan yang hosting semi dedicated / share hosting yang resource nya lebih gede jadi cukup tinggal pasang tak perlu banyak tweek

Pengalaman saya kemarin pakek aplikasi CBT , scripnya yang kurang di optimasi. penulisan ke mysqlnya memakan banyak resource. *saya pasang di shared hosting.

ngakalinnya di buat banyak subdomain dengan masing2 ada aplikasi CBT nya , ujian siswanya login per kelas..

coba perkecil size-nya, cukup 1gb saja, tidak perlu sampai 4gb

throughput dan iops-nya lebih besar contabo
jika perlu aplikasi yg banyak baca-tulis, gunakan yg iops besar
tapi pertimbangkan juga latency network terkait jarak dari server ke pengguna

sebagai pembanding, ini salah satu vps yg kami gunakan untuk keperluan erp
tidak se-intens ujian online, tapi saat jam kerja lumayan rame untuk entry data
