Is there a chance that something other than the performance of the ethernet driver is at fault here? For example, could the RAM be setup with a different number of wait-states (making the eCos test bed slower). Or could caching be enabled with Linux but disabled in eCos? -- Matt >> Can you help me to improve performance of eCos >> ethernet driver.
