Selamat malam Tuan-tuan dan para Suhu sekalian.

Izin bertanya dan minta pencerahan teknis. Kebetulan saya ada server fisik (bare metal, bukan VPS) yang menggunakan NVMe. Di dalamnya ada partisi Windows (NTFS) yang perlu saya mount di Ubuntu Server 24.04 (Kernel 6.8).

Saya iseng melakukan benchmark dengan dua metode mounting yang berbeda, dan hasilnya agak membingungkan saya (ada yang naik drastis, tapi ada angka yang turun).

Skenario 1: Mount pakai ntfs-3g (Default)
Saya mount biasa tanpa flag khusus (terdeteksi pakai ntfs-3g / FUSE).
  • Bench.sh (Sequential Write): Cuma dapat ~126 MB/s. (Terasa lambat banget untuk NVMe).
  • YABS (Fio): Speed Mixed R/W terbaca ~3.10 GB/s, tapi IOPS 4k cuma 76.9k.
Hasil Yabs.sh:

Skenario 2: Mount pakai driver ntfs3 (Kernel Driver)
Saya coba paksa pakai driver kernel baru dengan perintah: sudo mount -t ntfs3 /dev/nvme0n1p3 /mnt/windows_nvme -o defaults,noatime,prealloc,uid=$(id -u),gid=$(id -g)
  • Bench.sh (Sequential Write): Melonjak ke 1.1 GB/s (Naik hampir 10x lipat).
  • YABS (Fio): Speed Mixed R/W malah "turun" jadi 1.03 GB/s, TAPI IOPS 4k naik drastis ke 126.5k.

Pertanyaan saya untuk para Suhu:
  • Kenapa di Skenario 1 (ntfs-3g), hasil bench.sh hancur (100MBps) tapi di YABS speed-nya bisa tembus 3 GB/s? Apakah itu cuma caching/buffer RAM semata (phantom speed)?
  • Di Skenario 2 (ntfs3), meskipun speed YABS terlihat turun (dari 3GBps ke 1GBps), tapi IOPS 4k-nya naik 64%. Apakah aman disimpulkan kalau Skenario 2 ini sebenarnya yang lebih performant dan "sehat" untuk penggunaan real-world?
  • Apakah memang driver ntfs3 (kernel) sekarang sudah direkomendasikan untuk production menggantikan ntfs-3g?
Mohon bimbingan dan penjelasan teknisnya Tuan, supaya saya tidak salah ambil kesimpulan.

Dan kira kira lebih bagus mana, iops besar apa R/W speed besar? Rencananya untuk bikin paas kecil-kecilan pake docker swarm.

Terima kasih banyak.

ini saya nulisnya di hp susah banget :35:
