A bit faster. But I want to recover the below 1000 ms

Once more, a bit faster here.

Unfortunately the last build is very slow here. And this is the faster of 2, the second was 3224 ms.

I have also noticed a high CPU use, that does not translate into a faster simulation, at least in the benchmark scenario.

Confirmation?

the horror!

Confirmation or condemnation

[Knightpawn]

Very slow indeed compared to previous built

Run the benchmark with B1877 and B1892 to compare the CPU use in the resource monitor and this is the result.

As you see the CPU use has increased significantly, is visible in the graphic and in the average CPU %. In the graphic the periods of 100% use are much more common, also the drops to 0%. The average changes along the benchmark, but it is noticeable the difference between the 2 builds, in B1892 was up to 80%.

However the result of the benchmark is worse, why?

Exceptions, none in B1877 running the benchmark. Several in B1892, as commented in the Top Gun scenario thread.

May you test the last B1892?

But backup first your current Command.exe.

In the Command.ini file (Config folder).

This line is True or False?

RunCoreMultithreaded = True

[Ryzo90]

Back to back comparison during a CPU upgrade from Dual Socket Xeon 2640V4 to dual socket Xeon 2697A V4 both with 96GB RAM.

[Lakeend]

In the Command.ini file (Config folder).

This line is True or False?

RunCoreMultithreaded = True

False

I havent modified that myself.

[Nikel]

False

I havent modified that myself.

May you retry the benchmark? Changing it to True and saving Command.ini

In my case the benchmark changes from 1675 to 1554.
