新启VLAN访问服务器速度偏慢问题

为了工作需要，在内网汇聚层开了新的VLAN250，可以访问服务器，但速度明显比其它VLAN慢。其它VLAN访问服务器获取文件，大概10Mb/S，新开的VLAN250只将近3Mb/S。汇聚层两台3560三层交换机，互相做热备。设置了VLAN端口，做了HSRP协议，在ospfl路由协议里通告了VLAN端口。请问，一般是什么原因呢？

配置大概如下：

主：3560-01

inter Vlan250
ip address 10.252.250.2 255.255.255.0
standby 250 ip 10.252.250.1

standby 250 preempt
