Now I want to do a performance test of PPC with linux. Our board is FADS and MPC860T. I use the kernel from denx website(2.4.4). the test program is iperf. When I use the iperf on PPC+linux as server, I start the iperf on PC as client. I choose the options -n 300M -P 120 which mean I want to open 120 threads each one open a TCP connection and each preparing to send 300MB data. On PPC+linux I get the following output. "eth0: Memory squeeze,dropping packet" "__alloc_pages: 0-order allocation failed (gfp=0x20/0) I guess that the data to be processed exceeds the capabilities of PPC+linux. I wonder whether this could be solved by Linux ??? Thanks a lot for your kind help Best Regards. Zongjun Sun ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
