Do some high-concurrency new pressure tests per second cause F5-i10800 100% cpu usage

Do some high-concurrency new pressure tests per second and find that when the L4 of the F5 data sheet reaches one-fifth of the new per second, the CPU utilization of the device will reach 100%, and t...

I don't know how the L4 connections per second of the device data sheet is calculated. In practice, if VS is in Standard mode, it is estimated that when it reaches 25% of the new connections per second, the CPU utilization will be 100%.

F5-i10800:

VS in standard mode, 300K new connections per second(use irules) cause the CPU utilization 100%

VS in PerformanceL4 mode, 800K+ new connections per second(it not use irules) cause the CPU utilization 100%
