In case of on redundant peer is powered down, the connect timeout at startup of an UI takes a long time under Linux RHEL (probably with other Linux systems)
The solution is to decrease these both parameters by using sysctl as root :
# sysctl net.ipv4.tcp_syn_retries=1
# sysctl net.ipv4.tcp_synack_retries=1
This is not persistent after reboot. To maintain these settings, you can create a configuration file in /etc/sysctl.d/ as below
# File : /etc/sysctl.d/my_custom_settings.conf
# Custom settings for tcp_synack_retries and tcp_syn_retries
net.ipv4.tcp_synack_retries = 1
net.ipv4.tcp_syn_retries = 1
