Hi,

the Netra comes with a "360- or 440- MHz UltraSPARC-IIi, single processor, Superscalar SPARC Version 9" CPU, so you can use "--mcpu=ultrasparc --mtune=ultrasparc" with gcc. This is for gcc v3.x, gcc v2.x might require --march instead of --mtune.

HTH Christian

Thanks for the tip, I will use this gcc options.

Miles/Andrew polling increased dramaticly the latency for all traffic that passes trough the bridge and reduced the transmission rate also.

with polling:

rtt min/avg/max/mdev = 1.472/2.005/2.651/0.393 ms

without polling:

rtt min/avg/max/mdev = 0.642/0.735/1.111/0.134 ms

Thanks in advance
