Do you mean local as in LAN or local as in localhost? Local ping times, PC->LAN(100Mbs,full duplex)->Verdex 600MHz well windows reports 1/0ms. Verdex 6LP + wifi+sd -> wireless hub (WPA2/TKI+AES) -> LAN(100Mbs,full duplex) -> PC 8-10ms ;-). To contrast this against a linksys wireless hub (100mbs) I generally get 3-6ms from the LAN side PC->Hub. I don't think that DMA vs non-DMA will make too much of a difference. Re: low latency, there are probably things in the kernal such as the io scheduler and process parameters that may effect network latency. Oh with that "fix" you may want to prefix it with the verdex define, this is probably not a great hack it would be better to get to the bottom as to why DMA is not working, having just got wifi sorted out I might have a look but it probably won't be quick (busy). #ifdef CONFIG_ARCH_PXA #ifndef CONFIG_ARCH_GUMSTIX_VERDEX #define SMC_USE_PXA_DMA 1 #else #define SMC_USE_PXA_DMA 0 #endif #define SMC_USE_16BIT 0 #define SMC_USE_32BIT 1 #endif -- View this message in context: http://www.nabble.com/Garbled-ethernet-data-on-netmicroSD-vx-tf4503136.html#a12882963 Sent from the Gumstix mailing list archive at Nabble.com. |
