	%X This paper presents an architecture of current filesystem
implementations as well as our new filesystem SpadFS and operating
system Spad with rewritten VFS layer targeted at high performance
I/O applications. The paper presents microbenchmarks and real-world
benchmarks of different filesystems on the same kernel as well as
benchmarks of the same filesystem on different kernels – enabling
the reader to make conclusion how much is the performance of
various tasks affected by operating system and how much by physical
layout of data on disk. The paper describes our novel features–most
notably continuous allocation of directories and cross-file readahead
– and shows their impact on performance.
