I am a bit deceived over the performance of the 100 Base T network card on the HP979KS/400.  Ok, it is twice as fast as the 10 Base T (of what I had before). I get about 2.0 Mbyte/s or 16 Mbits/s.  I was actually expecting somewhere in the range of 80 Mbits/s.  The 3com switch  (model 3C16792A) I am using has 2.5 Mbytes of cache. I specified the maximum buffer size in NMGR i.e 50.  The funny thing is when I copy a file from one pc to another I get transfer rates of  115Kbytes/s.  I don't understand, PC's are supposed to be a lot faster.  The supervisor software that comes freely with 3Com does not give much info.  Some of the software out there cost $600 and up.  I am looking for a software that will show possible collisions i.e troubleshoot if necessary the network.  The 16 port switch that I have carry a 3Gbit/s bandwidth overall.  Should I have bought a more expensive unit for better performance?

Has anyone been able to obtain better performance on an HP9x9 box?

Thanks,
