In doing some testing I found that the Xircom RBEM56G is much slower in receiving than in sending.
RX (ftp get) 3610159 bytes received in 13.8 secs (2.6e+02 Kbytes/sec)
TX (ftp put) 3610159 bytes received in 0.57 secs (6.2e+03 Kbytes/sec)
The test is done with command line ftp between a DEC HiNote VP765 and a fast desktop machine connected by a 10/100 switch. The connections are 100baseTX and full duplex. I'm using Red Hat 6.0 with 2.2.13 kernels at both ends. The difference in speed is about 24 times! I am going to repeat the test with a cross-over cable to eliminate problems with the switch.
Is anyone else with this Xircom card getting good receive performance?
