Subject: Cygwin&Win32 file prefetch, block sizes?
Date: Tue, 2 Apr 2024 02:04:41 +0200	[thread overview]
Message-ID: <CANH4o6Mxai4_C=d1P93Prrimb8_H=trTwm-Eg+WBwpomN3tNJw@mail.gmail.com> (raw)

Hello,

Is there any document which describes how Cygwin and Win32 file
prefetch and readahead work, and which sizes are used (e.g. always
read one full page even if only 16 bytes are requested?)?

Quick /usr/bin/stat /etc/profile returns "IO Block: 65536". Does that
mean the file's block size is really 64k? Is this info per filesystem,
or hardcoded in Cygwin?

Thanks,
Martin
