Slow network speeds?

Pinchy · Apr 20, 2008, 01:55 PM

Im wondering if my network is running at the speed it should. Before I start, the hardware:

Linksys wrt330n wireless gigabit router
1/2/3 metre CAT6e network cable
Onboard gigabit network cards (ASUS P5b deluxe, Gigabyte G33M-DS2R)
Server with PCI gigabit card will be put in next week

Now going from a 10/100 network to a gigabit, I did expect to see over double the network speed. Over the network, I have no idea of my read speed, but my write speed is 6-8MB/s (starts at 10MB/s...taken from windows vista's "more information"). Then, for no apparent reason, it will drop to 2-3MB/s. Not always, but most of the time.

Both computers have two hard drives in RAID0. Should I be expecting more or is this about right? (Hard drive limitations?). The 8MB/s seems about OK (seeing as copying files on the local machine goes at about 12MB/s)..but why would it drop to 2?

I have both firewalls disabled (on each computer).

Also, I ran a quick network benchmark testing the "performance" of the network (not sure if its read or write) and it got average 24MB/s, max 32MB/s. Program is called AIDA32 using the network plugin. (Its the old everest).

Thx in adv

You can expect speeds between 20-40MB/s on average setups.
Have you enabled jumbo packets?

Thx for the fast reply

Is that read or write?

Also, I have never heard of jumbo packets. Assuming its in the network card properties or router settings.

they're called jumbo frames, it's weekend give me a break :P

Anyway, just go to device manager and check the options of the NICs.

Use a tool like Everst or Passmark Performance to monitor network speeds. You transfer rates are very slow (irrespective of jumbo frames). Something is not correct.
