Throughput and new connections per/sec might be up to 4 times slower in AWS for SR-IOV enabled instances.
Performance is 3-to-4 times slower than the license limit. Slow throuhgput and new connections per/second
This might occur when a BIG-IP virtual server is configured with a Standard profile.
If throughput performance is 3x-4x times slower than license limit for virtual servers with 'Standard' profile, consider disabling interruptible sleep. To do so, use the following commands to: 1. set the appropriate DB variable to 0 (zero), and 2. restart tmm: 1. setdb Scheduler.UnicAsleepRxLimit.LTM 0. 2. bigstart restart tmm.
Throughput and new connections per/sec are now comparable in AWS for SR-IOV enabled instances and in other instances.
