Q: This is my setup . Dlink modem with an SMC7004VBR switch.
2 computers with XP to connect to the switch .
Im trying a file copy 6meg from one computer to another . to be fast right? nope . it is slow as dirt . takes about 1 minute per meg! what am I doing wrong? the NIC cards are both set to show that it is not about the Internet and back 100/full.
tracert. I baffled.
task manager on a computer shows the network utlization be 0.5%
what else can I check?
Best Answer: alright, is other peoples' internet fast on these laptops? it might just be that the laptops themselves are slow.
and is your desktop plugged in, or is it also wireless? if it is wireless, then i'd check all the settings on your laptops to make sure everything is okay. it'll give you the "network cable unplugged" message because the linksys WRT54 is wireless, so you aren't physically "plugging in".

Hmm… all of those speeds seem slow to me… I'm constantly shuffling GB sized video files around… seem to be stuck at 33 megs per sec and full(? why?) CPU utilization on my Duron 800. Any ideas why my cpu gets maxed out? DMA is on, and Hard drives are the latest 7200 8 meg cache variety (independent benchmarks show 55+ megs per sec)
Any sites, guides devoted to getting max performance out of networks?
Just remember that the PC is still based on an interrupt-based architecture. When your NIC gets or sends a packet, it has to interrupt the CPU and have it stop and check out what's happening on the NIC. On 10BaseT, that's not that big of a deal, when you start pushing 30+Mb/s, things get busy, especially when you consider that you have to pull/push that data from the hard drive, causing more interrupts and more and more load on the CPU. Just for fun, try to create a RAM disk copy on both ends and copy your file to/from that, just to see if you have any performance.
Lastly, NETBios isn't the fastest of all protocols. Try using something like FTP (light overhead) and see how fast you can push things.

Re:197/15= 13megs/min
and it means… 216k/sec i think…
kinda slow i think…
my network runs like 3-7megs a sec…

I'll second everyones suggestions.
Most times (9 out of 10) a network performance problem is related to the cable. Once the cable is ruled out by replacing with a known good cable you can look elsewhere for problems.
Next comes drivers.
After that comes mucking with registery settings.
After that comes configuration.
Ok, I'm going to try new cables tomorrow…
I've shaved off some time playing with the settings… I'm getting 197 megs copying at about 15 minutes? Is that good?
Is there a free tool that can measure my copying speed between two computers?

Re:Oh, I'm not trying to defend myself. Just want to eliminate possible causes.
I'm glad people are giving me suggestions. Let me look at your suggestions and will report back. thanks!
Re:A way to assess it is to Install NetBEUI, bind file sharing to NetBEUI, and Unbind it from TCP/IP.
Try to exchange files again. If it is slow, it is probably a Hardware and or Drivers related problem. If netBEUI yields normal speed (about 8MB/sec.) then your TCP/IP, Firewall, Virus, setting has some incorrect entries.
BTW. Scott did not try to challenge the legality of your cable. But rather to find out whether it is commercially produced cables or ?Hand Made?. Lately a lot of guys are trying to "manufacture? their own cables, and big percent result in none functional or slow LANs.
Re:I got the cables from work… since I do work related work at home…
I want to rule out the nic cards since my transfer from the internet is actually faster than transfering between the two computers.
Re:Self made / home made / non-production cables?
Check your NIC drivers.
Those seem to be th two "biggies" lately.
Good Luck
Scott
