I am using Intel® 82579V, 1 x Gigabit LAN Controller(s) and CAT 6 cable , however my network utilization is limited to 15%-35%.
I know that practical speeds are lower but is there nay way i can increase this throughput , any maximum throughput experience ?

On a 1Gbps getting 25% Max utilzization is extremely slow.

Am i missing soemthing tat needs tobe corrected .

I am working on LAn and ocnnected to a server using HP Procure 2810 series switch.

More about : network speed limited

What are you using to measure throughput on the network? Hard drive transfer, memory transfer, network bandwidth tester?

If using hard drives, 15 to 35% would be about it....thats150 to 350 Mb/s which is pretty good for mechanical drives
SSD drives should go higher
Memory transfer tests should push it close to 80 to 90%

Are you running any Qos on the switch?

I am trying to Render video files in premier pro from share drive.

The way it is setup is all project files and clips are stored in the shared drive on a local server.
The server is connected to he Hp switch and thn computers connected over the LAN.

When i try to render anything or copy files - Network utilization in Task Manager shows maximum 25% Network utilization .
I am using Bandwidth monitor tool and another tool NetMeter .
Both show around 200-250 Mb/s or 25-40 MiB/s

Question 1 : Why do I get 25% utilization , How can I improve it?
Question 2 : What is the maximum data-rate I can expect in IDEAL conditions?


I tweaked and played with intel Nic card and it got slightly better ( enabling jumbo packet , increasing buffer size for TX/RX ) but i am not sure where its heading not very concrete results.

I am going to try and see if the HP switch has some settings that can increase the throughput.

Any Recommended tools / Software for LAN BW tests?

Client computers have SSD and File Server is all SAS with 6GB Raid card.
Network cabling is new and CAT6.

As sturm said, you can't improve it. Your speed is only as fast as the slowest link in the chain, in this case, your hard drive. To improve it, you need faster drives and fiber channel is too expensive for home use.

Faster client drives or Faster server drives?

I'm interested to know if you have found any solutions to your dilemma. I do know that LAN Aggregation could be a possible solution if you haven't yet looked into it.

As stated, the solution is faster hard drives. The drive isn't going to accept data faster than it can write it. You can put a wolkswagon beatle on the autobahn, but it doesn't mean it's going to drive as fast as a ferrari.
