Blunted Posted August 13, 2005 CID Share Posted August 13, 2005 i want to know what speed i can get with a 100 mb nic. both comps are over 2.8 ghz pentium 4HT with 1 gig of ram and 2 gigs in the other and both of the have the same kind of nic(exact model) and both set to full duplex and i cant get past these speeds. 9604.11 kB/s is 78676.87 Kbps Or 78.68 Mbps ::: 9.38 MB/sec can i go faster ? should i buy a gigabit switch and nic cards?

VanBuren Posted August 13, 2005 CID Share Posted August 13, 2005 hey Blunted how did you measure that speed? Best thing is to use taskmanager and see how many % of 100Mbps your using during the transfer, use a very large file and it will be even more accurate VanBuren Quote Link to comment https://testmy.net/ipb/topic/6841-need-help-with-speeding-up-lan-transfer-rates/#findComment-70387 Share on other sites More sharing options...
Blunted Posted August 13, 2005 Author CID Share Posted August 13, 2005 i am using my firewall and got 9604 kb and used your calculator and it came to that. also my card goes to 76% and spikes to 80% sometimes. i am using cat 6 and the wires are 1.5 feet each and connect to a switch that does 200mbps. both cards are on full duplex and the cpu is at 40 to 50% anything else you need to know that might be able to help out?

VanBuren Posted August 13, 2005 CID Share Posted August 13, 2005 what speeds do you get if you use "Auto" on the NIC Quote Link to comment https://testmy.net/ipb/topic/6841-need-help-with-speeding-up-lan-transfer-rates/#findComment-70389 Share on other sites More sharing options...

VanBuren Posted August 13, 2005 CID Share Posted August 13, 2005 try using the 100 Mbps cablenutfile version 7 that should do the trick, also you might need to update NIC drivers VanBuren Quote Link to comment https://testmy.net/ipb/topic/6841-need-help-with-speeding-up-lan-transfer-rates/#findComment-70395 Share on other sites More sharing options...
Blunted Posted August 13, 2005 Author CID Share Posted August 13, 2005 cool i'll try it and see what happens Quote Link to comment https://testmy.net/ipb/topic/6841-need-help-with-speeding-up-lan-transfer-rates/#findComment-70396 Share on other sites More sharing options...
Blunted Posted August 13, 2005 Author CID Share Posted August 13, 2005 i did the cablenut and i get about the same speed but i cant find drivers for it. linksys lne100txV4 model and still lookin for drivers Quote Link to comment https://testmy.net/ipb/topic/6841-need-help-with-speeding-up-lan-transfer-rates/#findComment-70504 Share on other sites More sharing options...
Blunted Posted August 14, 2005 Author CID Share Posted August 14, 2005 found drivers and it says the old ones are better. lol what would you do van the man?

VanBuren Posted August 14, 2005 CID Share Posted August 14, 2005 I would have tested those drivers, you can always manual reinstall them but since it claim to be the latest its probl not going to get any better then this. It might also be a problem in the switch, if you have a TP cable, bypass that switch and connect the both PC Quote Link to comment https://testmy.net/ipb/topic/6841-need-help-with-speeding-up-lan-transfer-rates/#findComment-70619 Share on other sites More sharing options...
Blunted Posted August 14, 2005 Author CID Share Posted August 14, 2005 if that doesnt work could it be the nic cards just cant do it ? otherwise i am stumped Quote Link to comment https://testmy.net/ipb/topic/6841-need-help-with-speeding-up-lan-transfer-rates/#findComment-70621 Share on other sites More sharing options...
Blunted Posted August 14, 2005 Author CID Share Posted August 14, 2005 i connected them directly together with a crossover cable cause it wont work with cat 5 or 6 but my other ethernet cards do. i am stuck at about 9800 kB/s = 80281.6 Kbps Or 80.28 Mbps ::: 9.57 MB/sec with spikes upto 11507 kB/s = 94265.34 Kbps Or 94.27 Mbps ::: 11.24 MB/sec 1 thing i noticed is that it will stay at around 9,800 with 1 download and with more downloads it goes faster. is that right?

VanBuren Posted August 14, 2005 CID Share Posted August 14, 2005 I dont know what the problem could be, but my guess is the network adapters 11.24 MB/s should be solid, and the network graph should show around 98-99% at that speed if you add TCP overhead 11.24 x 1.1 = 12,364 MB/s with 10% overhead VanBuren Quote Link to comment https://testmy.net/ipb/topic/6841-need-help-with-speeding-up-lan-transfer-rates/#findComment-70660 Share on other sites More sharing options...
Blunted Posted August 14, 2005 Author CID Share Posted August 14, 2005 i think its the cards too cause it goes faster with the more i download. i downloaded about 20 files to make to go faster in this pic Quote Link to comment https://testmy.net/ipb/topic/6841-need-help-with-speeding-up-lan-transfer-rates/#findComment-70661 Share on other sites More sharing options...
Blunted Posted August 15, 2005 Author CID Share Posted August 15, 2005 2 of my comps have gigabit nic's so i connected them directly with cat 6 it was 50 feet and got this speed. what is the limit a comp can take in or causes it to be limited to a certain speed?

Blunted Posted August 15, 2005 Author CID Share Posted August 15, 2005 i used the calculator on this site and got this speed. 15187.12 kB/s is 124412.89 Kbps Or 124.41 Mbps ::: 14.83 MB/sec Quote Link to comment https://testmy.net/ipb/topic/6841-need-help-with-speeding-up-lan-transfer-rates/#findComment-70948 Share on other sites More sharing options...
VanBuren Posted August 15, 2005 CID Share Posted August 15, 2005 I havent tested that out, but you could try this add a zero to your DefaultReceiveWindow and DefaultSendWindow so they are 8192000 VanBuren Quote Link to comment https://testmy.net/ipb/topic/6841-need-help-with-speeding-up-lan-transfer-rates/#findComment-71004 Share on other sites More sharing options...
lazy8 Posted August 22, 2005 CID Share Posted August 22, 2005 this is more so because I'm curious. but wouldn't you be limited by how much your HD can read and write the data?

scoob8000 Posted August 25, 2005 CID Share Posted August 25, 2005 12.5MB/s is 100m.. The most you'll likely ever see in windows is 8 or 9.. Seems the Windows TCP/IP stack, even tweaked cant crank out much more. Now, in linux on the otherhand I've seen 11.5-12.0MB/s speeds FTP'ing across a lan..

Blunted Posted August 25, 2005 Author CID Share Posted August 25, 2005 i get 11,500 on windows now and sometimes hits over 12,500 on 100 mb but now i want to speed up my gigabit lan if its possible. the fastest i hit was about 140 mb and i dont know about verizons test server cause it give off bad test results and duplex modes but it says( The theoretical network limit is 137.02 Mbps ) so that seems accurate. i am gonna mess with it tomorrow and see if i can tweak cablenut and mess with some other things to get past 140 mb.

Did you do any tweaking. I love Kerio, but I've noticed it slow down lan transfers sometimes.. Mainly for FTP..

Blunted Posted August 25, 2005 Author CID Share Posted August 25, 2005 look at the 100 mb lan pic above its the 1st pic. kerio does slow it down a little bit but i still get around 9000 Kb a sec with it on so its not that bad. i didnt tweak much but i messed around with cable nut and gonna finish it tomorrow and see what i can get on gigabit ethernet.
