ioBenchmark: RawFileReader_read_peaks benchmark

In fgcz/MsBackendRawFileReader: Mass Spectrometry Backend for Reading Thermo Fisher Scientific raw Files

RawFileReader_read_peaks benchmark

Description

derives numbers to evaluate time performance for reading a single spectrum in dependency from the chunk size (how many spectra are read in one function call) for reading different numbers of overall spectra.

Usage

ioBenchmark(
  nv = c(1000, 5000, 10000),
  sizev = c(8, 16, 32, 64, 128, 256, 8, 16, 32, 64, 128, 256, 8, 16, 32, 64, 128, 256, 8,
    16, 32, 64, 128, 256, 8, 16, 32, 64, 128, 256, 8, 16, 32, 64, 128, 256),
  rawfile
)

Arguments

nv	number of spectra to be read.
sizev	number of spectra write and parsed in one single junk.
rawfile	the Thermo Fisher Scientific raw file.

Value

data.frame

Examples

eh <- ExperimentHub::ExperimentHub()
EH4547  <- normalizePath(eh[["EH4547"]])
(rawfileEH4547  <- paste0(EH4547 , ".raw"))
if (!file.exists(rawfileEH4547 )){
  file.link(EH4547 , rawfileEH4547)
  }
S <- ioBenchmark(1000, c(128, 256, 128, 256), rawfile=rawfileEH4547)
