Hi, so I have a USB drive im sharing through Samba. The drive is encrypted with bitlocker and im using dislocker to decrypt it. This problem does not occur with bitlocker disabled.
When I test file operations, speeds start at what I expect (~30 MB/s) but quickly drop down to ~3 MB/s.
I was looking for some guidance on interpreting the result of htop. This is what it looks like when this is happening:

Two main questions around this -
1. According to the overview up top, im only using around half the total CPU capacity of my device.
2. Breaking it down by core, it looks like the 4th core is getting the most usage, at around ~85%. But it's still not maxing it out, and how come that number isn't reflected up top?
Based on this, can it be determined that the CPU load from dislocker is the bottleneck here? When im not using it, SMB goes fine.
