When sending logs to a F5 load-balancer the throughput and bandwidth are limited to what they should be.
原因
The F5 load-balancer has not been configured for high performance in regards to the communication of TCP handshakes.
解决办法
Please work with the F5 vendor to ensure that the Layer 4 (performance) configuration is used rather than the default.
Layer 4 handles TCP acknowledgements more quickly and has better performance in regards to bandwidth/log flow allowing for more logs to be sent in higher volumes.
