Problems with not using memory. Agents manager uses HDD, not memory

[Masa Hori]

I have three computers, A, B, and C.

I am running backtests on B and C from A through Local Network Farm, but the memory consumption on B and C is strange.

B and C have spare physical memory, but the HDD or virtual memory is being used.

The folder used by B and C is the "Tester" folder in the "MetaTrader 5 Strategy Tester" folder on the HDD.

Software and version

A Oanda MataTrader5 ver5.00 build 4468

B MetaTester5 agents manager build 4522,AVX

C MetaTester5 agents manager build 4460,AVX

Photos of task manager for ABC attached

A is 8GB per agent

B is 2.3GB per agent

C is 5.7GB per agent

Though it is the same backtest, the amount of physical memory used is different

Why is this?

B has 24 cores, 48 ​​threads, and 128GB of memory

B uses 30% of the physical memory and has a lot of free space

In B, I run 10 or 20 backtests, but no matter how many I use, the memory usage remains the same.

How can I make it use the physical memory?

I set the virtual memory usage to zero on the Windows OS, but it didn't work.

I'm thinking of trying an older build of agents manager, but where can I get the older version?
