    Old machine faster

    I have two dell desktops. Both use the same firewall and av software (Norton Int. Sec.). Both route thru the same Cisco E3000. Both have gigabit nics. My DSL speed is 3 MB. The old machine consistently (many measurements at Numion) is faster (2.9-3.2 MB). The new machine is significantly slower (1.7-2.4 MB). Both are wired connections with the router.

    Old Mach: XPS 410, Intel Core 2 Duo @ 2.4ghz, 4 gig ram, IE8, Vista 32
    New Mach: XPS 9100, Intel i7 @3.2 ghz, 12 gig ram, IE9, Win 7-64

    Any idea's where to start with getting more internet speed with the new setup?

    Did you test with the firewall off? That would be the first thing I would try.

    Things I'd check on the new machine are.
    1. Crapware that came with the machine and is phoning home constantly.
    2. Are the drivers up to date? Just because the machine is new to you doesn't mean the image the drive was built from may be way out of date with windows updates and driver updates for the wired NIC.
    3. Viruses, Root Kits, Malware of all sorts.
    4. What software is auto starting at boot, i.e. update checkers, etc.

    Hope this helps.

    Ok, I've tested this thing repeatedly with firewall and AV off, and with it on. Latest test (I know it depends on the I'net speed, but...) was to download a copy of Open Office. At 150 meg it took the old machine about 8 min, 12 sec. The new mach took 1 hr, 31 min.

    I've removed as much crapware and phone home as I could find. The machine is virus free and drivers are up to date. I ran msconfig and shut down anything that looked like it might interfere. I'm still getting speed test results of:
    Old Mach: 3234 kbs
    New Mach: 2243 kbs

    Upload speeds are comparable at about 433 kbs.

    Dell Support can't find a problem.

    Any more idea's that I might try?

    What OS are you running?

    Have you tried tuning your TCP stack?

    Finally found the cure!
    It took about 4 hours with Dell support testing and telling me everrything test's ok. They then asked if I was satisfied. My response was "No, and I will be returning their $1800 computer." They offered to supply an Intel NIC to compare with. Installed it and found it to be much faster. On the follow-up call they indicated that I should also try a mother board swap while the warranty was still in effect. Ok, put the new one in. The service tech could not believe the difference between the two mother boards. The new one is up to speed. His last comment was that the old board would probably be tested (remember it tested ok previously) and would probably be (sadly) used as a replacement for someone else.
