Projeto Descrição

fio is an I/O tool meant to be used both for benchmark and stress/hardware verification. It has support for 19 different types of I/O engines (sync, mmap, libaio, posixaio, SG v3, splice, null, network, syslet, guasi, solarisaio, and more), I/O priorities (for newer Linux kernels), rate I/O, forked or threaded jobs, and much more. It can work on block devices as well as files. fio accepts job descriptions in a simple-to-understand text format. Several example job files are included. fio displays all sorts of I/O performance information, including complete IO latencies and percentiles. Fio is in wide use in many places, for both benchmarking, QA, and verification purposes. It supports Linux, FreeBSD, NetBSD, OpenBSD, OS X, OpenSolaris, AIX, HP-UX, Android, and Windows.

Alguns problemas de compilação foram fixados em algumas plataformas selecionadas, onde problemas com CC substituem ou falta de apoio de relógio do CPU iria quebrar a compilação. Configuração do tamanho = para cargas de trabalho de zipf/pareto foi corrigido. Flutuante de matemática para o relógio da CPU foi acelerado e melhorado, mais reduzir a sobrecarga. Um ponteiro nulo potencial referência sobre verificação de IO e fixou-se eventos de colocar.
A few build issues were fixed on a few select platforms, where issues with CC override or missing CPU clock support would break compilation. Setting of size= for zipf/pareto workloads was fixed. Floating math for CPU clock was sped up and improved, further reducing overhead. A potential null pointer dereference on IO verification and requeue events was fixed.
