我有一台 HP ProLiant 服务器，它有 4 个物理网络端口。eth0并且eth1绑定在一起。今天我们遇到了服务延迟的问题，结果发现eth0速度先是下降，然后上升到 1000Mbps，然后又下降，然后上升到 100Mbps。
为什么接口的速度不同？原因是什么？是否有可能防止这种情况再次发生？
这是 Bonding 配置：
DEVICE=Bond0
IPADDR=x.x.x.x
NETMASK=x.x.x.x
GATEWAY=x.x.x.x
ONBOOT=yes
BOOTPROTO=static
USERCTL=no
DEVICE=eth0
HWADDR=XXXXX
TYPE=Ethernet
UUID=XXXXXXX
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
USERCTL=no
MASTER=Bond0
SLAVE=yes
DEVICE=eth1
HWADDR=XXXXX
TYPE=Ethernet
UUID=XXXXXXX
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
MASTER=Bond0
SLAVE=yes
和粘合状态：
Bonding Mode: load balancing (round-robin)
MII Status: up
MII Polling Interval (ms): 0
Up Delay (ms): 0
Down Delay (ms): 0
Slave Interface: eth0
MII Status: up
Speed: 1000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: XXXXXXX
Slave queue ID: 0
Slave Interface: eth1
MII Status: up
Speed: 1000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: XXXXXXXX
Slave queue ID: 0
