About this task
Monitor the actual number of aioservers
started during a typical workload using the following command:
pstat -a | grep aioserver
You may have to increase the number
of aioservers if:
- The actual number of active aioservers is equal
to the maxservers and
- The CPU utilization of all the aioservers appear
to be even (indicating that all aioservers are used)
- You continue to see the Warning: lio_listio
returned EAGAIN messages
The MetaLink Notes discusses the issue and provide recommendations
for maxreqs, minservers and maxservers:

use AIO servers and what determines how many are used?
