Hi,

This is jsut a newbie question

How to measure the speed if I know the Ip address.

is any other way to measure?

[root@localhost root]# ping xx.xx.xx.xx.
64 bytes from xxxxxxxxxxx: icmp_seq=0 ttl=242 time=72.400 msec
64 bytes from xxxxxxxxxxxxx: icmp_seq=1 ttl=242 time=68.254 msec
64 bytes from xxxxxxxxxxxxxxxx: icmp_seq=2 ttl=242 time=67.180 msec
64 bytes from xxxxxxxxxxxxx: icmp_seq=3 ttl=242 time=66.301 msec

What is the speed of the server?


I Just want to know how to measure?


Thanks

Please correct me if I am wrong.


so in average the speed is 888bytes/per sec?

so is their back bone is oc3?


Thanks

There use to ba an old program I knew called tcpblast which attempted to measure the through put of a connection, when I used it, it was fairly accuracte, however it accurately measured the weakest link in the path to the target. Keep in mind people out there really dont like you using this program, its like flood pinging.

i jsut want to measure the speed of the IP cuz thinking to get
a server from their?

Is my calulation is ok?


so in average the speed is 888bytes/per sec?


Thanks

Hi Stephenn,

what you are doing is not the way to measure network burstability or network capacity. Ping is meant to measure how much time it takes for a data packet to be travel from your computer to their server and back to your computer again (round trip). In this case, the data packet took an average of around 72 ms to reach their server and back to you again.

The best and rather accurate way to measure burstability is to do download test from that server. For example, you can try (from within their server, though it will be hard for you to do if you don't have access to their server) to download ftp://ftp.uu.net/uumap.tar.Z and see how long it takes to download this 8MB of file. This is also not the most accurate way to measure it but it will give you a good indication of the network burstability/capacity. For example, the host can claim they have an OC3 backbone, etc. But their servers will not be directly connected to the backbone but rahter to a switch. The port on the switch itself can be 10 or 100Mbps (or even 1Gbps) in which case your burstability will be limited to the switch port.

I hope this helps ...

Thanks.

Well it took around 80 sec for 8320KB(8M) to download .

its around 104KB/Sec

so this port speed is 100Mbps. Am I correct?


When you mean 100Mbps => bit per second right ??)


thanks
again

I can't tell you the port speed, but 104KB/sec is around 832Kbps, just under 1 Mbps. The download speed too is varied depending on several other factors, how far the server is from the download site and also how good the peering from the server to the download site. But if you want to know how big is the switch port speed, try to transfer file between servers. For example, I just transfered files between one server to another server linked to a 100Mbps switch and I got around 11MB/s transfer rate, or around 88Mbps.

Yes, small "b" is usually used to refer to "bit" and capital "B" for "Byte"

Have fun :)

Thanks for your all info.
