Emachine T3512-Need help with throughout



  • Hi everyone, I need help with low throughout and low cpu usage.

    I have this E-machine T3512. Here's specs:
    CPU: Intel Celeron TM D 3.20 Ghz / 533 MHZ FSB / 512KN L2 Cache
    Memory: 1GB
    HDD: 200GB
    NIC: 2x 1GB PCI and 100 MB integrated chips Realteks
    pfSense running i386 2.0.1

    Throughout: 20-22 Mbps and cpu still not reach maximum when take a speedtest.net

    Second E-machine T6520's specs:
    CPU: AMD Athlon 2.4 Ghz
    Memory: 1GB
    HDD: 250GB
    NIC: 3x 1GB PCI and 100 mb integrated chips Realteks
    pfSense running i386

    Throughout: over 120 mbps and cpu usage still not reach maximum.

    Internet: Cox Communications 30mbps/3mbps on Cisco DPC3010 with 7/4 bonding channels. Second backup internet, same ISP but 20/2 on SB5120 with 4/4 bonding channels.

    After I installed and I took a test with some of speed but mostly I only getting 22 Mbps with pfSense but over 100 mbps without pfsense. I reinstalled with AMD64, same results. Everything is working but this is odd that it only getting 22mbps download but over 20 upload. I'm trying to figuring what's going on with throughout.

    Other thing I watching the CPU usage, it staying 0-3% but it never go above that. It's pretty good but I don't know what's going on with download throughout.

    Any Idea if it can pushing the throughout?



  • Anything interesting in the system log? With that system, you should be able to reach alot better throughput.



  • First, realteks are junk, and may be saturating your bus.  Also, eMachine systems love to go cheap where you can not see it.  (Like chipsets)

    Can you get an Intel motherboard and some Intel nics to test with?  I would not be suprised if they work much better.

    Note:  This is not about CPU.  It is chipset and nic.  Intel chipsets have the most complete implementation of the PCI specs.  I spent some time working with PC based DVRs and many other chipsets had timing issues that were deal stoppers.  As to Nics, Intel nics put almost everything in hardware, so they have the least load on the system.



  • Are you by any chance running the traffic shaper and/ or Squid?

    Those could be limiting your bandwidth (if you're measuring via web based tools like speedtest) if the configuration of the shaper is not done properly.

    I agreed with you. I'll buy intel instead of Realtek. Realtek are piece of shit however, at most in the system actually are realteks nics. I'm still thinking about dell server is fit for my needs. All dell server are intel chipset and nics. Can I pick dell 2950 for beginner and is it supported for pfsense?

    Will check it but the Realtek are sucks. Intel are way to go!

    I checked that out. It look seem to me that the configuration hasn't been changed to limit the bandwidth. I just let bandwidth go full at this time. Thanks for ask! Though.

    Not always.  Some will have Broadcom Chipsets.

    yeah the 2950s do have Broadcom NICs, but they're good solid NICs too. You won't find cheap junk NICs in any good server.

    That said, a 2950 is gigantic overkill for home use and a big drain on power, I wouldn't use one for home use. But that eMachines desktop? I wouldn't use that for anything.

    I just checked out the specs of the Emachines - the short of it is that I wouldn't bother using them for anything more than web browsing on WinXP.
    Both units use the Radeon Express 200 series chipset.  Absolutely horrible stuff that is the low end of the budget IGP based chipsets in that generation.

    In all likelihood, the chipset is holding you back with that many devices chained off the PCI bus.  If you can enter the BIOS (CMOS), try bumping the PCI Latency timer to '128' if the setting is exposed.  It might help a little when using the PCI devices but there is no guarantees.

    … a 2950 is gigantic overkill for home use and a big drain on power, I wouldn't use one for home use. But that eMachines desktop? I wouldn't use that for anything.

    100% agree on both statements.  I have a couple 2850's at home (VMWare cluster), twas bad on my power bill, replaced them with a couple old Core 2 Duo HP's, similar performance, 1/4 the power.

    E-machine wise, you might be able to re-use some of the parts if you find a cheap motherboard that'll fit the case and CPU; not sure that I would trust the power supply, though.  Might be better off finding an older Dell or HP.  A Dell Optiplex GX280 has a PCI-Express slot and a P4 with Hyperthreadding, which should do pretty well if you need multiple ports with a standard PCI intel card for 100Mb and a PCI-Express card for Gigabit (The on-board is Gigabit, but I can't remember the chipset.)  If you don't need as much throughput, an even older GX260 could be decent, earlier P4 (maybe HyperThreadding), onboard Gigabit; add a PCI Gigabit card and you should be able to push a decent amount of data for cheap, possibly under $50.

    Well. That's beginner to do. I have some Cisco and ubiquiti equipments. For Cisco, I have couple of aironet and POE switches with gigabit and for ubiquiti, 4 of them but two are act as back up WAN 2 and 3. other two are for our wifi for outdoor with WPA2 Enterprise.  how much power bills you get if you using dell server?



  • @choppergage:

    how much power bills you get if you using dell server?

    Depends on your power cost. 2850s and 2950s pull a steady 250 wt, so 6 Kwh/day. Average US power cost is $0.12/Kwh, which would make that $0.72 per day, an average of a bit under $22/month.

    That sounds about right, my bill dropped probably around $40/mo when I turned mine off.  Other circumstances went on around the same time that made it hard to tell, but I'm pretty sure your calculation is pretty accurate.
