computer slows to a crawl when receiving data on Lan

11 posts in this topic

Hey, Looking for an idea why my computer would slow to a crawl when i'm transferring data over my lan.

Right now as it's set up i have a network place on windows server 2003 r2 setup for another computer on my lan. When i take any info from the other computer to the computer with server 2k3 r2 on it, the server 2k3 r2 slows down so much that i can do fuck all with it till the data is finished transfering.

What do you guys think?

It doesn't make sense to me. I have a fairly decent processor and more than enough ram for the computer. Could it be the NIC? It is a gigabit, but the router is use is 10/100 mb so i know the router would bottleneck but i don't think the transfer speed would effect computer performance.

Any feedback is welcome

Thanks

Is it even slow when you are downloading things off the internet?

How fast is the hard drive? Have you installed the correct drivers for the SATA or IDE controller? If you're doing something that generates a lot of hard drive access and you don't have this right, sometimes it can make the entire machine crawl. If you're also hitting swap while it's doing that, the machine can outright stop.

I think what he may be getting at is if you're transferring images, movies or other files that Windows will try to make thumbnails for and you have the folder open in explorer, it will be generating thumbnails. This is expensive in itself, but since the files are not finished, it can be even worse.

When i download torrents and other stuff, no it doesn't slow down.

This is my hard driveit has also done this with the previous 80 gig drive. I do have an error on my SCSI/RAID controller (the same as my SATA controller) said that it was set to IDE. Don't remember where i saw that though. Could this be the issue?

When i posted this i was transfering Virtual Machine files, but it has happen with any other files as well.

Not to sure if this could be the reason but you might want to look into IRQ settings for your HD and LAN and any other computer resources to see if there is a problem there.

I would fire up wireshark or tcpdump and take a good look at the packets going through while the slow-down is happening. Look for stuff not related to the file transfer like re-authentication or maybe even excessive collisions and re-transmits. Could be a number of things. Also I would fire up some good PC monitoring stuff like perfmon. And examine what's going on on the server.

Time to hone your troubleshooting skills. :D This is the kind of stuff I love.

Post some traceroute results on here. Maybe a certain device is choking up the flow.
