[Linuxsampler-devel] disk streaming performance with iso

[raf]

Hello,

would there be a performance issue when using SFZ engine reading WAV fles from a mounted ISO instead of a standard folder structure containing the WAV files ?

Since that implies layering two file systems on each other and accordingly
requires two file system stacks to be processed on every read() call, this
definitely means a performance penalty. I never benchmarked it, but my guess
is if the the inode size in both file systems is large enough, then
performance might be "okay".

thank you for the answer, i'm surprised that inode could have an
influence but i have to admit i'm not a specialist of filesystems.
For now i'm testing with a stripped down version with wav samples
exported from the iso files. I'll probably move to the iso files
later, so i'll report here wheter it works "okay" or not.
