This is basically my setup at home:

2015-04-28 12_49_36-Drawing1 - Visio Professional.jpg

I have gigabit cards in both machines, network cables as above, both machines reporting 1000mb/s connected, but when I copy something across from Study PC to HTPC, I get 10-11MB/s.

When I bypass the 5 port switch, and plug the HTPC straight onto the 8 port switch, I get faster speeds.

Any ideas?
 
Every connection you have is a potential "leakage point"

So the more connections, i.e switches, you have the more you will lose speed.
Which is why if you bypass the one switch your speed picks up.

You can then further connect your other devices to the switch.

yes it is.

the access point is in another building, the 5 port switch is at the window, the other one at the other side of the house.

i want/need a technical answer why i'm not getting gigabit transfer speeds.

I want to see if I plug everthing else out of the 5 port hub except the HTPC, if it still gets 100Mb speed

What kind of distances are we talking about here?
Your network cables can be up to 100 meters in length before you need another hub/switch.
As was said above, the less joints and connections, the better.

There are many potential problems.
Cable can be badly joined
Cable can be not up to spec for Cat5e
Switches can be faulty (power surges/age/exposure to the elements or sun)

1) Make Sure you are using Cat5E or Cat6.
2) Check the end points and re-do if necessary.
3) Remove unnecessary equipment if you can
4) Use a Cable Tester if you have one.
 
You definitely got 1gbps between the two switches?
 
The gigabit refers to the speed it should be of the reaching, but doesn't necessarily mean that you will actually transfer at those speeds since interference, bad cables, improperly functioning hardware, slow hard disks, and many other things can affect actual speed.

For instance, copying 100Gig between 2 SSD's and 100 GIG between two 7200RPM mechanical drives will give different results.

I have a similar setup to him and I'm seeing 30 megabytes per second between machines. Limited by the hard drives.

I don't see why not... if I take the cable between the two switches, and instead of plugging it into the 5 port switch, i plug it into htpc, i get the gigabit speed.

I'll do some more trails and tests this afternoon and see if I can narrow down the issue.
 
Also check if the cable isn't running near sources of interference like power cables , RF cables etc.
That also has a big influence on speeds.
