标题: 千兆网络，内部服务器传输速度只有10M/S，正常吗？
内部2台IBM机器，交换机是千兆的3750，服务器也是千兆网卡，但是我在内部2台机器相互ftp时，速度只有10M/S左右，这个速度正常吗？感觉小了很多啊

你先要排除服务器自身的瓶颈问题。或者直接用工具或软件工具测试网速。\r\n\r\n另外帖交换机和服务器相连接口的show int 信息。

服务器和交换机接口匹配的结果是千兆全双工吗？

内部服务器传输速度只有10M/S?局域网也不只

作者: 北极星 时间: 2009-10-19 16:01
如果是100MB的话，我想是正常的，因为100MByte *8 =800Mbit，应该还可以的。\r\n\r\n呵呵，不好意思少看一个零。\n\n[ 本帖最后由北极星于 2009-10-20 22:06 编辑 ]

多了个0啊。\r\n\r\n哈哈哈哈。\n\n[ 本帖最后由 ssffzz1 于 2009-10-19 16:32 编辑 ]

这个是100M的速率，1000M的端口我试过在最多80几M。\r\n\r\n问题如果只考虑网络的原因：\r\n1、两台服务器是否在同一交换机上，如果不上需要看一下上行端口的利用率。\r\n2、服务器是否在同一网段，中间是否有网络限制。\r\n3、什么交换机，是否硬件问题。\r\n浅见，供参考。

一般来说忽略刻意设置，大都还是硬件瓶颈\r\n\r\n交换机和网卡千兆，中间弄个5类线，恐怕得出10M/s这样不奇怪了

* Cisco Catalyst 3750G-24TS--24个以太网10/100/1000端口和4条SFP上行链路\r\n * Cisco Catalyst 3750G-24T--24个以太网10/100/1000端口\r\n * Cisco Catalyst 3750-48TS--48个以太网10/100端口和4条SFP上行链路\r\n * Cisco Catalyst 3750-24TS--24个以太网10/100端口和2条小型可插拔（SFP）上行链路\r\n\r\n以上是3750交换机的配置情况。如果你的交换机不是带G结尾的型号，又没有SFP光纤口。\r\n你的10MB/S算是很高了，我家里用FTP的只有7M/s左右。

LS再仔细算算。\r\n\r\n这个是100M的速率，1000M的端口我试过在最多80几M 。这个数值是差不多的。

作者: gammachang 时间: 2009-10-20 09:17
LS请看仔细，我极度怀疑LZ连接两台机器的是百兆口

查看服务器自适应的速率是多少，双工模式匹配情况，10M/s慢了点啊，不正常。

能确定网络设备和网线都是千M的吗?\r\nftp做了速度限制吗?\r\n\r\n我试过,用迅雷下载内网的文件,千M最快的传输速度是93M多

看看网卡和交换机的链接速度
