Description
  • V tomto papíru je prezentována architektura existujících filesystémů a také našeho nového filesystému SpadFS a našeho jádra operačního systému Spad s přepsanou VFS vrstvou zaměřenou na I/O s vysokou rychlostí. Papír obsahuje mikrobenchmarky a benchmarky při reálné zátěži. Jsou benchmarkovány odlišné filesystémy na stejném jádře a stejné filesystémy na odlišných jádrech, což umožňuje zjistit, jak moc je rychlost různých operací ovlivněna jádrem operačního systému a jak moc samotným způsobem uložení dat na disku. Papír popisuje naše nové vlastnosti - zejména souvislou alokaci adresářů a mezi-souborový readahead - a ukazuje jejich vliv na rychlost. (cs)
  • 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.
