Hi hawq community, Anyone know that why we turn off DoS protection in hawq by setting net.ipv4.tcp_syncookies to off in /etc/sysctl.conf? Any other reason from hawq perspective other than below two more from operating system perspective?
1) increase the number of concurrent tcp clients 2) reduce cpu overhead for creating and processing the syncookies. Though the overhead is tiny BTW: HAWQ turn off DoS protection <http://hdb.docs.pivotal.io/210/hdb/install/install-cli.html> while Greenplum Database enable DoS protection <http://gpdb.docs.pivotal.io/4320/install_guide/prep_os_install_gpdb.html> by default. Best regards, Ruilong Huo
