go hard on the mems, run re-run, many add the pause in the command line to configure some extra settings between each run and weird but on some platforms  WIN7 is faster :p

переходите к mems, запускайте повторный запуск, многие добавляют паузу в командной строке, чтобы настроить некоторые дополнительные настройки между каждым запуском и странным, но на некоторых платформах WIN7 работает быстрее : p

I ran the task manager during the test, I chose the real-time mode, and even then the result was better
I do not understand, how do I set the priority of real-time to run? probably need to do something with the files

вы можете использовать процесс lasso или что-то похожее для установки близости и приоритета для pifast до его запуска.

Many thanks for the link! I will try to improve the result
about pifast really little information

I do not really understand how to do this, on a single-core processor there will be an increase?

On a single core cpu the extra load of process lasso will equal a net loss. On a multi core cpu you set the affinity for pifast and every other process to seperate cores, then you can also set the launch priority of pifast. 

If you're on a single core cpu and just want to increase the priority then you can follow the steps here to edit the batch file https://www.wikihow.com/Make-a-Program-Start-at-High-Priority-(Windows) for multi core systems process lasso should be better as you can also set the core affinity.

I read all this, did just that, this is not enough
and much from there only worsened the result...

The easiest way to run pifast in real time priority, is to run the hexusFastR shortcut from the rar I've attached :) No need for PriFinity, Lasso, or any of those tools. 

Other than that, PiFast pretty much likes what SuperPi does. Priority, affinity, lighten the OS a bit, RAM timings, sometimes also maxmem and a simple copywaza (depending on the platform). Put a folder on desktop that has 700MB files inside, or 1GB, whatever you like and just copy it once to C, then run it multiple times until you get "the best" score. @Leeghoofd is right about the win7 thing too, I've noticed that sometimes, pifast is faster on windows 7 on some platforms. For all the older processors I bench though, I use Windows XP of course.

Я говорю о той части, где написано о настройке приоритета для любого файла с помощью программы  PriFinity 2.5

I do not want to use any programs

Try running pifast in fullscreen mode by modifying properties for a given window name. It should be easier to get a good run.

I for a full-screen start approximately so.

 

Code for Pifast.bat

@echo off
SetLocal EnableExtensions EnableDelayedExpansion
IF "%~1"=="max" (
  SET params=%*
  start "Name of the Batch" /MAX %0 !params:~4!
  EXIT /B
)
ECHO new params: %*
pause
launcher pifast41.exe  hexus.txt

Code for RUN_Pifast.bat

@echo off
Pifast.bat max

Я для полноэкранного запуска примерно так.

 

Код для Pifast.bat


Код для RUN_Pifast.bat


 

in full-screen mode, I knew how to do it before, thanks
I needed only to learn about the real-time mode
but this already figured out

Another thing I've found about pifast (Stelaras has confirmed it too) is that if you use a really really chopped up windows xp, you actually make it worse. A 150MB Win XP installation is perfect, no less though.
