Is this high? for me it is because it's more than 0.

With AIX 7 being used more frequently in network deployment environments, and with common use of workload partitions to help manage resources, you should be aware of all the different applications and environments you need to optimize your network deployment.
IBM AIX IPTRACE INTENSIVE SERIES
When we look at "netstat -p tcp" and calculate packet retransmitted/data packacts sent it is more than 17% and according to the performance guide it's far too high (must be <5-10%)Īnd when we look at "entstat ent0" i see a lot of interupt errors. This three-part series on AIX 7 networking focuses on the challenges of optimizing network performance. The networkcard is a Gigabit Ethernet-SX PCI Adapter (14100401) We have a IBM P-series server & AIX 4.3.3 I have encountered a lot of network issues on our networkcard.
