We negotiate rsize mounts (and it can be overridden by user) to typically 4MB, so using larger default I/O sizes from userspace (changing to 1MB default i/o size returned by stat) the performance is much better (and not just for long latency network connections) in most use cases for SMB3 than the default I/O size (which ends up being 128K for cp and can be even smaller for cp). This can be 4x slower or worse depending on network latency. By changing inode->blocksize from 32K (which was perhaps ok for very old SMB1/CIFS) to a larger value, 1MB (but still less than max size negotiated with the server which is 4MB, in order to minimize risk) it significantly increases performance for the noncached case, and slightly increases it for the cached case. This can be changed by the user on mount (specifying bsize= values from 16K to 16MB) to tune better for performance for applications that depend on blocksize.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
