[AccessD] OT: Network speeds

John,

<<It is not cat 6, in fact the whole house is cat 5.>>

  This is something you really need to look at.  Cat 5 is only certified up
to 100mb/sec.  It will go faster, but it is not recommended.  5e can go up
to 1000 mb/sec.  I would be surprised if you simply had 5 everywhere.  It
wasn't that long ago that you moved there.

  The other thing to check (assuming you did your own wiring) is that the
connectors are on properly.  They need to be wired in a specific pattern
(white/orange, orange, white/green, blue, white/blue, green, w/brown,brown)
and the last twist in the wires should be within 1/2" of the end of the
connector.

  But with all that said, your getting so little speed, I think your problem
lies else where as the rest of the house is wired the same and seeing much
higher speeds.

  A simple ping test from one to the other should show <1 ms response if
everything is basically sound.

   I would also suggest swapping some ports and seeing if the problem moves,
just in case you have a bad port on one of your switches, but I doubt it
will.

   And are these truly switches or are they hubs?  If the latter, you should
have no more then three devices in a chain (hub, hub, hub, and device is a
no-no).

Jim.

It is not cat 6, in fact the whole house is cat 5.

I have a pair of "servers", one of which really is - dual cpu 16 core 64 gig
ram.  That is at the 
far end in the basement under the living room.  In that same location is a
former workstation which 
is now my unraid file server.  They plug into a gigabit switch.  Coming off
of that is a wifi 
hotspot (router with the dns turned off serving wifi) sitting in the drop
ceiling in the basement, 
under the living room floor providing wifi to the front part of the house.
Another cable going off 
to a small 100 mbit switch upstairs behind my TV.

In the middle is another gigabit switch about 80 feet (of cable) at the
place where the internet 
comes in to the house.  So that switch basically has a cable from the above
mentioned servers, a 
cable from my router / wifi (which is of course 100 mbit) and a cable going
upstairs two floors to 
my home office.  At my office end is another "server" and my workstation
laptop.  That has a gigabit 
switch and a wifi hotspot (router with the DNS turned off just serving
wifi).

I have done file transfers on the SQl Server from disk to disk and get
150-400 mbytes / sec.  This 
is all either SSD raid or raid 6 hard disk.

I have done file transfers on the VM server on the other end of the house.
Again very good speeds, 
150 MB / sec or better.  Raid controllers or SSD.

But between these two machines... 10 MB / sec transfers.  It certainly looks
to me like the LAN.
