亲，看一下arm9 + lwip + dm9000
本帖最后由 jomin 于 2012-6-28 10:19 编辑在arm9+linux + dm9000 的时候网速能跑到5M左右，
但是换成ucos+lwip，却只能1M左右，是程序有问题呢还是lwip本来就跑不快？
TCP server listening.
UDP server listening.
TCP connection established ...
Receiving from client, packet size 1k ... 967.49 KByte/s

都arm9了，何必上lwip？ korgo 发表于 2012-6-28 10:04 static/image/common/back.gif
都arm9了，何必上lwip？
要干很多的活，而且要快，于是就上了ucos+lwip，我看到linux中BSD socket 处理数据都是在一个较大的缓冲区中进行，而lwip是将数据缓存分割成很小的内存块处理的。理论上lwip必定比BSD SOCKET 慢，但是会慢到1M吗？ jomin 发表于 2012-6-28 10:08 static/image/common/back.gif

不好意思，我没跑过arm9，但是感觉arm9应该接很大的ram。。。 korgo 发表于 2012-6-28 10:19 static/image/common/back.gif

ram是很大，我是说lwip的处理机制 ucos里有几个任务？ winterw 发表于 2012-6-28 10:22 static/image/common/back.gif

如果裸奔lwip带宽能有多少啊? LZ ,您好，能把源码发我参考下吗，搞了好久没成功 lvyecc@gmail.com 亲，可以将您的ARM9 + ucos+lwip代码给我参考下吗，有个问题卡了好久 lvyecc@gmail.com lvyecc 发表于 2014-2-15 19:21
亲，可以将您的ARM9 + ucos+lwip代码给我参考下吗，有个问题卡了好久

见邮箱。。
请帮忙看下哦.谢谢 mark......................... 本帖最后由 sddzycnq 于 2014-4-3 14:24 编辑
理论上不应该有这样大的差异。很怀疑你的LINUX下的速度测试。再就是看到你的ucos输出是自己计算的速度。是否也与计算方法有关？ 没有启用DM9000aep内部硬件加速,快不了!
