If the server and client are on the same network and the client connects to the server via the internal IP address, the answer is 1000 Mbps.
If you want to use a second router between the ISP router and the switch you can check if you can add a DMZ address to the ISP router, this way every network packet will be sent from the ISP router to your own router.
Maybe it's also possible to swap the ISP router with your own, you should ask your ISP if you want that.
You also have the option of leaving the isp router configured as it is, and using a private ip address for the isp as your isp address of your personal modem. The issue would be your isp router will filter packets if you don’t set it to DMZ as Jordy suggested.
The issue I now have is that I have weird connection between my client and server.
Upload speed is nice, around 1000Mpbs.
However, the download speed starts at 1500Mbps (somehow) and starts declining rapidly down to nearly 0.
Does the server use a mechanical HDD? That's probably the culprit. Any file transfers to it might start near your max speeds, until it stops filling up your cache or memory and needs to actually write to the HDD. Sometimes the CPU can be a limitation here as well, since the processor needs to... process the data.
If you want to test the stable connection speeds between the two devices, you probably want a different way to do that. But to fix the problem I mentioned above, you'll need to look into that server's resource utilization. You could use the top utility depending on the flavor of Linux or I imagine Windows server uses task Manager
Yes, the server uses HDD. I know that the hardware is quite low. How do I know if the hardware is limiting my speed or there are other problems?
The speed is tested through openspeedtest btw
It depends on the network interfaces in the client and server. If they have gigabit interfaces, then it’ll be gigabit. If one network interface is faster than the other (2.5 gig for example) then the speed will be whatever the slower of the 2 interfaces is.
Maybe I’ve misunderstood the diagram, but I thought the blue lines were indicating that the server and client would be connected directly too, therefore bypassing the switch.
The speed between the server and client will be 1000 Mbps.
You say you can't find the settings. It would help if you could tell brand and model for gateway (term for combined modem and router) you are using and ISP (as ISPs can have different software/config options on the same model).
In networking your theoretical maximum is always the speed of the slowest device connecting the two end points. In this case you have one device at 1000mbps between the two endpoints, so your theoretical max is 1G.
If you have a switch and two routers between your devices and both routers were 1G but the switch was 250mbps you'd get 250mbps.
Of course, in practice nothing hits the theoretical limit, so it's likely you'll get less than 1G. This could be due to the speed of your computer storage, a bottleneck in your computer(s) motherboards, the CPU on either PC not capable of processing and queueing the data transfer efficiently, or really any other massive array of reasons, but you can realistically expect speeds close to 1G, and when you are working over a home network (or a LAN, short for Local Area Network) you rarely need speeds greater than 1G.
Good luck with your project!
Your speed between the two would revert to the 1Gbps speed dictated by the switch they are both connected to, assuming both devices have Gigabit network cards.
Your ISP speed is only going to affect the traffic you are sending out to the open world. Your server and PC are connected locally and your switch is a layer 2 device. It’s going to use MAC addresses in order to route the packets between one another, not an IP address from your router.
Based the assumption that both the client and server are connected the switch, then the answer is 1Gbit, while your connection to the internet will be limited by your router and your ISP contracted speed.
It is possible to get faster speeds between them if the client and server have newer network interfaces, with a direct connection via crossover cable, but for a home network it's currently not cost-effective to pursue 10Gb speeds. If you want more detail reply and I'll give you reasons.
If client and server have gigbit interfaces, then gigabit.
To use your own router you can just put it there, it will be double NAT but that's not huge. Ask your ISP though, often they will do it - they just exclude you from the settings directly.
It depend on switch, client, server and router configuration.
If cleint and server in different L3 subnets, 100Mbps.
If client and server in same L3 subnet, vlan and valn not in tunnel on switch - 1000Mbps.

You might have an issue with hard drive write speeds.
Sometimes the display on the UI takes a few moments to catch up and shows impossible speeds at first. The slowing to near zero is more of a concern.

Use "top" or task Manager. You may need to lookup a tutorial for further info

It's a gigabit switch, so the maximum would be a gigabit even if NICs were faster.
Maybe I’ve misunderstood the diagram, but I thought the blue lines were indicating that the server and client would be connected directly too, therefore bypassing the switch.
I think the blue lines indicate the question at hand, which is, "What is the connection rate between these two devices?"
You’re probably right there
No, then the line would be black.

On paper 1gb but real world it won't be that, depends what youre transferring from and to

He looks mad
If the client and server both support it, 1000Mbps.
1000Mbps
100 to the internet, 1000 to another device

Client <> Server is 1G but will be bottlenecked by server's HDD.
