…now server performance is slow…

What performance is slow? What are you comparing against? What performance tuning has been done in the past? What is the system configuration? …memory pools? …activity levels? …available memory? ..DASD capacity and % utilized?

What is running in the system when performance is slow? If it is slow compared to some earlier time, what has happened in the meantime? Did performance change after the IPL? …after the router was restarted? Why was the router restarted?

Is this really a V4R5 system or did you mean V5R4?

…but it was not like this before…

Before? Before what? All of the above questions need to be answered in order to make guesses.

However, Graybeard52 has made an example suggestion that is a reasonable candidate. If a compile of a simple addition program is the only significant activity, I wouldn’t expect a cache battery to show such a large difference; but it’s possible depending on answers to the other questions.

As you talk about compiling, its evident that you are a programmer. The IBM i comes with a wealth of performance analysis capability. some web research, and dipping into IBM.com will turn up a methodology for you to analyse what may have altered.

One of the first items may be to examine which IPL was used. It’s possible to IPL using different sets of microcode, and if a powerdown is so unusual you may need to start at the very beginnning of system verification
