I test the network performance in two system using iperf and netperf i
Gigabit LAN.
my system configuration is

node A : Intel Xeon Dual Processor (2.8 GHz) with 2 GB RAM
node B : Intel Pentium III Dual Processor (1.2 GHz) with 1 GB RAM

i get only 

552 Mbps (before implementing IPsec)
45.5 Mbps (after implementing IPSEC)

why the throughput is so low. please suggest me.

regards
bhaban
