what is the use of APP_NET_HEAP_SIZE defined in appconf.h ?.Is there any performance improvement if we increase this heap size ? and also where it is used in bsp?..

APP_NET_HEAP_SIZE specifies the size of the heap allocated for the TCP/IP stack. The minimum value for this variable is typically 512k. I have worked with customers who had to set this value as high as 1.5M.

If your application makes heavy use of TCP, be it simple sockets or HTTP, increasing the network heap can make a tremendous performance difference.


we have changed APP_NET_HEAP_SIZE in appconf.h to 0x120000 but there is no change in our application performance and I repeat my question “Where this size being used in BSP or application”
