Hi folks,

I have two servers in the same network segment and with the same hardware.
The First work as a router and second is a DNS, a HTTP, and Postifix server.

I realized a test, I tried to copy a 1Gb file from servers to my machine.


I am very bother because this:

Server 1 transmition speed 250kb/s
Server 2 transmition speed 15kb/s (!!!!!!!!!!!!!!!!!!!)






Some Server 2 datas:

-CPU is often IDLE
-Memory average utilization is 80%
-Interface traffic average is 8k
-few users have shell access and run pine only
-some network connection number , as following:
Active Internet connections

Proto Recv-Q Send-Q Local Address Foreign Address (state)

tcp4 0 10237 bh.4037 mta-v20.level3.m.smtp ESTABLISHED

tcp4 0 0 localhost.domain *.* LISTEN

tcp4 0 0 bh.domain *.* LISTEN

udp4 0 0 localhost.domain *.*

udp4 0 0 bh.domain *.*

-Interface configuration is

fxp0: media: Ethernet 100baseTX <full-duplex>;

- switch point is 100full

- There are not errors ou colisions on interface;



Could you help me?

Eicke.
