Threads specified for specific file type

[fullxml]

I have moved 100s of TB files using FFS in last many years. There are many suggestions I have in regards to making FFS more effective and powerful (and maybe faster). One suggest is, if we can have specialized threading. We can have multiple threads running on multiple files (RAIDs maybe). And number of threads could be assigned for specific file types, e.g. Thread 1, 2 for jpg/jpeg/image files, thread 4,5 for video files etc. We can assign these categories and assign file types to those categories and those categories could be assigned to the thread.

So a threads could be assigned as following --
Thread --> assigned category (same as grouping but retains for future reuse)
Thread --> assigned file type (one off work, temp in nature)
Thread --> assigned temp grouping of file types (one off task work, temp in nature)

What is a thread to you? Are you referring to a process thread or how thread is used in FFS?
Either way, you provided a suggestion but didn't say how this could be an improvement.
