PFS3 is faster than SFS. I haven't been able to check IceFS but my understanding is that IceFS performance is close to SFS.

SFS slows down considerably over time, while PFS3 doesn't. I have no experience with IceFS here, but I'd think it doesn't slow down over time like SFS.

PFS3 doesn't do large files and has a partition size limit of 107GiB. IceFS has clear edge there.
