Understanding Manycore Scalability of File Systems
We analyze the manycore scalability of five widelydeployed
file systems, namely, ext4, XFS, btrfs, F2FS,
and tmpfs, by using our open source benchmark suite,
FXMARK. FXMARK implements 19 microbenchmarks
to stress specific components of each file system and
includes three application benchmarks to measure the
macroscopic scalability behavior. We observe that file
systems are hidden scalability bottlenecks in many I/Ointensive
applications even when there is no apparent
contention at the application level. We found 25 scalability
bottlenecks in file systems, many of which are
unexpected or counterintuitive. We draw a set of observations
on file system scalability behavior and unveil several
core aspects of file system design that systems researchers
must address.
