LAN not able to handles very large interactive files

Windows 10 Pro 22H2 with 32 GB RAM. I have 5 systems on Ethernet LAN. I often use an interactive chess program run from the master system A with 4 slave systems B--E. Aquarium IDEA is the controlling program on A.

Slave systems have engines that are first started manually on all the slave systems by an old program (orginally DOS) called "RTHomeserver". When the engines (large .exe files) are about 50 MB or smaller, then I can run the 51 physical cores (and chess engines) on the 4 slave systems in real time

However, the latest engines are 68-78 MB. When I try to use these large them (.exe files) for the 51 physical cores on the slave systems, only 6 of 51 cores on the slave systems are responsive, and work interactively with master program.

Are there Windows settings that can increase the capacity of the LAN? Or could there be a bottleneck in my LAN because of 1 Gps speed?
Thanks to the experts

Are you using ChessBase ?

Have you tried to connect via SSH + InBetween instead of using RTHomeServer.exe + wine ?

The engines communicate in plain text so I doubt it is a network limitation, more of a memory bottleneck.

I'm far from an expert in that field, But You might need to replace your kernels on the engines and enable large pages if not already done.

Malok: I'm using Aquarium/IDEA and RTHomeserver (I don't know what "wine" is in computer terms.)
I did try using SSH + InBetween as I was told it was much more up-to-date with regard to Windows LAN than the very old DOS program RTHomerserver. However, I was never able to get my master system to communicate with a slave system using SSH + Inbetween. SSH is very complicated to setup.

Are all pcs syncing at gig speads often they drop back if you have old network cables that could effect it try doing file transfers to find actual speed

Samuria, that's an interesting idea. The network cables (some snaking through the walls) are from 2010 or so. I have one up-to-date master system and 4 older slave systems. The slave systems have older network interface cards. How would I carry out your test of file transfers from master system to each of the slave systems to see actual transfer speeds over the LAN?
Thanks, Johanna

But still the question remains, Are you using Chessbase ?

"Wine" is a Dos / Windows emulator... Your slaves are not Linux based at the moment ?

If it's the case you are running a msdos network stack. And you could really be nearing the top of it.

I think You need a big and tedious software update. If you are able to switch to SSH it would make your life easier. If your Slaves are indeed running linux + Wine, you will probably need to update your kernels on every slaves.

A network bottleneck would not reduce the number of core usable / in use. But would make the whole thing slower.

Hi Malok:
I'm not using the Cbase GUI but rather Aquarium/IDEA, as I mentioned. I'm not using Linux, just plain old Windows 10 with 5 systems on the LAN. Thanks for the advice to switch to SSH/InBetween. I spent two weeks on it in September and could not get the systems to recognize each other. I've heard that SSH is much better than the old RTHomeserver.

I don't know what Aquarium/IDEA is, but it sounds like a protocol limitation than anything. It's like FTP. You could have a very fast fiber connection and due to the way the FTP protocol works it's slow. Well, slower than WeDAV.

So with this in mind, what is the protocol being used over the Ethernet connection? That may very will be your limiting factor. The 1 Gbps connection is more than adequate, unless you're only utilizing 100 Mbps over that Ethernet cable as was mentioned. You'd have to test that.

Click Start -> Settings to open Windows Settings. Click Network & Internet.
Click Status in the left panel.
In the right window, click View your network properties link under Change your network settings.
Under Properties, find the network adapter, the Ethernet or Wi-Fi, and find the speed next to Link speed (Receive/Transmit).

I think I got to where you wanted me to on one of my slave systems, though Windows 10 description slightly different from yours: Change adapter Status/Network Connections (Realtek PCIEe 2.5 GBE controller/ View Status of Connection:
Speed 1.0 Gbps.
Thanks, Johanna
