Skenario Pengujian

Pengujian :1. Pengujian pertama menggunakan

single tier

2. Pengujian kedua menggunakan multi tier (masing-masing tier menggunakan 2GB)

3. Pengujian ketiga menggunakan multi tier (masing-masing tier menggunakan 4GB)

Lingkungan Pengujian

Performansi jaringan dalam keadaan stabil dan jaringan hanya digunakan untuk proses pengujian saja

Mesin (tier) yang diuji hanya menjalankan service application server.

JMeter direstart setiap pengujian

Mesin menggunakan OS windows server 2008 64 bit

Kesimpulan Pengujian di Presentation Tier

Hasil response time multi tier lebih baik dibandingkan single tier.

Single tier hanya mampu menangani beban sebanyak 400 user

Multi tier hanya mampu menangani beban sebanyak 450 user.

Dalam pengujian saat ini, kapasitas memory tidak menunjukkan perbedaan hasil yang signifikan.

Kesimpulan Pengujian diWeb Service Tier

Web service masih memerlukan perbaikan lagi, jika dilihat dari grafik response yang selalu naik menunjukkan pola yang jelek.

Pengujian berhenti sampai multi tier menggunakan memory 2 GB
