I have for some time longed for a tool that would run in both Windows and Linux and be able to test the raw speed of the network between two endpoints. Now, half accidentally, I ran into this thread: Slow Gigabit Network - Win XP. And there it was: iperf.
With iperf I found that the bottlenecks were the actual pieces of software doing downloads, not the network itself. I managed to pull some 300+ megabits per second over TCP with gigabit link between nForce gigabit NIC and Netgear PCI NIC, and 700+ megabits between the said nForce NIC and Realtek TRL8111B integrated on Riitta’s Asus M2A-VM motherboard. Satisfactory to say the least.
This is just a quick report to help friendly googlers.
We today disassembled a Lifebook S7010 to examine problems in the cooling fan. Unfortunately after opening it we found nothing in the cooler we could have fixed, tho the thermal paste was in bad shape and we changed it; hope it helps the cooling somewhat.
However, when assembling the system back we got it working but the backlight was not working. Suspecting broken inverter we tore the machine back apart but as we had not touched it, we found it strange to have broken it.. The problem was solved when I screwed back the screws securing the D-Sub external VGA connector to the chassis - after fastening them the backlight worked like new.
Seems the inverter is grounded with the screws that also hold the VGA connector in place. Talk about kludge..
