Saya menggunakan FileZilla 3.10.3 dan PSFTP 0.63 (Putty). Adakah yang bisa membantu saya mencari tahu mengapa throughput yang saya dapatkan sangat jauh berbeda antara kedua klien? Itu tidak bisa hanya merupakan kelemahan dari protokol SFTP, karena FileZilla (dan WinSCP) jauh lebih cepat! Terima kasih sebelumnya.
Saat menggunakan FileZilla untuk terhubung ke server yang sama menggunakan beberapa protokol, saya mendapatkan throughput "baik"; ~ 1.2MBPS untuk satu file besar. Ini lognya:

Saat menggunakan PSFTP untuk terhubung ke server yang sama menggunakan protokol yang sama dan mentransfer file yang sama, saya mendapatkan throughput yang jauh lebih lambat. Saya akan memperkirakan sekitar 150kbps (melihat I / O byte di task manager Windows 7). Ini lognya:
