Performance of dhcp fail over protocol

[loganathan Govindaraj]

Hi

i understand your point i have pasted the dhcp server configuration below
please let me know whether the configs are right


failover peer "failover-dhcp" {
  primary; # declare this to be the primary server
  address 192.168.1.2;
  port 651;
  peer address 192.168.1.3;
  peer port 652;
  max-response-delay 10;
  max-unacked-updates 10;
  load balance max seconds 3;
  mclt 3600;
  split 128;


failover peer "failover-dhcp" {
  secondary; # declare this to be the secondary server
  address 192.168.1.3;
  port 652;
  peer address 192.168.1.2;
  peer port 651;
  max-response-delay 10;
  max-unacked-updates 10;
  load balance max seconds 3


with this the performance of the server is pretty low i mean 1 transaction
/sec .Do we have to modify any configurations
