title: Increase Initial TCP Congestion Window to 10 name: tcp_init_cwnd.stp version: 1.0 author: anonymous keywords: network tcp socket guru subsystem: network scope: system-wide status: proposed exit: user-controlled output: trace on-exit description: Run the tcp_init_cwnd.stp script in the background to override a kernel's default tcp cwnd value to 10, which has been found to improve latency for web server type workloads. The script prints a count of cwnd value changes when it is stopped. test_check: stap -g -p4 tcp_init_cwnd.stp test_installcheck: stap -g tcp_init_cwnd.stp -T 1
