On Azure with 3.5GB 2vCPU configuration, only 1 tmm is started
Only allocating 1 tmm can cause under-utilized CPUs in VMs in public clouds when RAM is not multiple of 2GB/per CPU.
BIG-IP Virtual Edition in Public Clouds.
None.
The logic for determining number of CPUs to be used by BIGIP was changed to take into account different Cloud VE configurations like these: * 2 vCPU / 3.5 GB RAM * 4 vCPU / 7.0 GB RAM * 8 vCPU / 14.0 GB RAM Now BIG-IP will assume 1.5GB RAM/per CPU and better utilize above configuration using all available CPUs.
