Create a script for comparing tcrypt speed test logs.
The script will systematically analyze differences item
by item and provide a summary (average).
This tool is useful for evaluating the stability of
cryptographic module algorithms and assisting with
performance optimization.
Please note that for such a comparison, stability depends
on whether we allow frequency to float or pin the frequency.
The script produces comparisons in two scenes:
1. For operations in seconds
================================================================================
rfc4106(gcm(aes)) (pcrypt(rfc4106(gcm_base(ctr(aes-generic),ghash-generic))))
encryption
--------------------------------------------------------------------------------
bit key | byte blocks | base ops | new ops | differ(%)
160 | 16 | 66439 | 63063 | -5.08
160 | 64 | 62220 | 57439 | -7.68
...
288 | 4096 | 15059 | 16278 | 8.09
288 | 8192 | 9043 | 9526 | 5.34
--------------------------------------------------------------------------------
average differ(%s) | total_differ(%)
--------------------------------------------------------------------------------
5.70 | -4.49
================================================================================
2. For avg cycles of operation
================================================================================
rfc4106(gcm(aes)) (pcrypt(rfc4106(gcm_base(ctr(aes-generic),ghash-generic))))
encryption
--------------------------------------------------------------------------------
bit key | byte blocks | base cycles | new cycles | differ(%)
160 | 16 | 32500 | 35847 | 10.3
160 | 64 | 33175 | 45808 | 38.08
...
288 | 4096 | 131369 | 132132 | 0.58
288 | 8192 | 229503 | 234581 | 2.21
--------------------------------------------------------------------------------
average differ(%s) | total_differ(%)
--------------------------------------------------------------------------------

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.
