Also shared memory listeners should reside in all CPU VPs, so, make this: NETTYPE ipcshm,6,30,CPU # Configure poll thread(s) for nettype NETTYPE soctcp,2,25,NET # Configure poll thread(s) for nettype NUMAIOVPS 2 # Number of IO vps This is too low, even with KAIO enabled. You will experience slowdowns when lots of updates to the message log have to happen (ie when you are busiest). Make it: NUMAIOVPS 6 # Number of IO vps Then monitor onstat -g iov. If there are more than one AIO VP with an io/wup column value less than 1.0 you can drop some. If there are NO AIO VPs with io/wup less than 1.0 you need to add more. Add two at a time. Beyond that I'd like to see output from: onstat -D onstat -d onstat -P onstat -g iov onstat -g iof onstat -g glo Art S. Kagel <SNIP>
