LAN Testing

It seems that I can never get upload speeds over 4Mbps. Is this because my account is probably not activated yet? I have tested over 100Mbps connections, from different routed subnets, the same subnet, directly connected via a cross-over cable, and for every test the download and upload speeds never reflect the true nature of the connection. Occasionally, the download will state 60 or 30 Mbps but mostly 10Mbps.

Any ideas?

Is this with any speed test? Are you referring to my test and if so, which one, the flash speed test or the java speed test.

Regards,

Jim.

I have had the upload issue this gentleman has reported. Although I have been observing how the broadband speed test works (wich is the version I'm personally using), and I may have an idea as to why.

I have another program I use to determine speed on my computer, and when I use the auditmypc speedtest while using the other software, I notice something interesting. The download test gets somewhere between 60-80 mbit, which is acceptable on a 100mbit lan. The upload actually only gets between 4-6mbit even though its located on 100mbit lan.

I have 2 theories. The first is that the uploaded file is too small. I have observed transfers that "wind up," i.e. they start slow and fill the network connection to capicity. So the upload speedtest never reaches capicity because the file being transfered is finished befor that time.

The second has to do with the type of transfer. For example, If I transfer files using microsoft file sharing (smb) between my main server and any machine in my office, I get an average of 40-50mbit. I can fill that up to the 80mbit mark by starting multiple transfers, but a single one will not fill up the pipe. I then download a file from the same server using IIS instead, and I get 80mbit right off the bat. Soo... If you were using different types of protocols to transfer the file up and down, we might get varying results...

Anyway, just off the top of my head.

There is an issue with size on the flash speed test, and for most standard connections, it is not noticeable. However, on a very large pipe, it will be noticeable. If you make the graphic file (the 12MB file) larger and try again, I'll bet your results will improve.

As for the Java speed test, you can increase the size of the zip file if you are having issues - you're not, right?

Excellent ideas and I really appreciate them ryeager!

Best regards,

Jim.

I too am having this issue, and have been looking for a speed test utility that is fast enough for quite some time. The one from oogla(?) that is also written in flash seems to be decent, but still not good enough. It reports my speed at 81meg download, and 62meg upload, using I believe 31 meg files.
The AuditMyPC test shows 33.6meg download, and 3820kbps upload. And this is on a gigabit connection. However, I have some very limiting factors.

I am going to a Kuro box, which is a small PowerPC processor box with 128 megs of ram, and I'm using a CompactFlash disk for storage. Reading/writing files will be SLOW.
The box is dedicated solely for speed testing, and has a gigabit ethernet connection. I'd love to put the transferred files into a ramdrive, but I dont think I can make a big enough ram drive to hold the size files I'd need.

The solution I was wondering about is, how hard would it be to use something like "/dev/urandom" (in the Linux world) for the input file? (or maybe some other device, like /dev/ram if security isnt a big issue).
The odd part is I don't want the test to take forever on a slow connection, but there needs to be enough data there that if there is a connection over 100 megs, theres enough data to do a real test...? Or is the speedtest app smart enough to only send data for a certain amount of time? If so, I can just increase the size of the jpg file... to as much as I can fit on a ramdisk while still allowing the system to function.
