Question regarding settings for streaming video content (> 20GiB larger)

[calexandre]

Hey all,
I'm trying to configure blobfuse2 for a video streaming application with recording feature and would like optimize it for the following scenario:

• It will handle big streams with 4 to 5 hours long using standard 1080p h264, which means each recorded stream may reach about 20GiB
• Blobfuse2 is mounted on a VM size Standard F4s v2 (4 vcpus, 8 GiB memory)
• The storage account is a Premium Storage Account with Block Blob configured.

Currently using the poor man's benchmark tool dd if=/dev/zero of=/home/azureuser/blobfuse-mount bs=100M count=10 oflag=dsync I'm getting roughly 115MB/s.

Do you think its possible to squeeze some additional throughput using blobfuse2?

I would love to hear your thoughts on this...

This is the configuration I'm using:

allow_other: true

logging:
  type: syslog
  level: log_warning

components:
  - libfuse
  - stream
  - attr_cache
  - azstorage

libfuse:
  attribute-expiration-sec: 120
  entry-expiration-sec: 120
  negative-entry-expiration-sec: 240

stream:
  block-size-mb: 64
  max-buffers: 16
  buffer-size-mb: 128
  file-caching: false

attr_cache:
  max-size-mb: 1024
  timeout-sec: 3600

azstorage:
  type: block

"stream" is not a good option to choose here. Use "block-cache" instead. You can refer our sample block-cache config here
