sknks, when using a 10Mbps pcmcia network interface, the Network Utilisation (TaskMan) indicates increasing usage as i increase network traffic (downloads etc), all the way upto 88%. however, when using a 100Mbps interface, the same gets stuck at 0.47%, no matter how much traffic i push. networking gurus, anyone to shed some light on this? what / where / why is the bottleneck?
<m.b>
0.47% or 4.7% ? 10 Mbps [Half-duplex ] = BW of 1 MB/sec 100 Mbps [Full-duplex] = BW of 20 MB/sec 88% of 1 MB/sec = 880 KB/sec (880KB/sec) / (20 MB/sec) = ~ 0.45 = 4.5% Where is your download source? The most accurate way to check your bandwidth is to transfer data to/from RAM between two machines, time the transfer and check the BW. There are an inordinately large number of tools out there what will do this for you.
