Some high-level advice: Profile everything you can to see where your bottlenecks are. If you don't have bottlenecks, simulate enough load that you do. I am frequently surprised by what turn out to be the slow parts of my code. At a high-level, you can use tools like top, vmstat, iostat, iotop, etc. to check whether it's CPU, memory, or disk space that you're running out of first. For CPU, you can use top to see which process is using most of your CPU, the database, app, or something else. Inside your app, you can use Perl's profiling tools to see which parts of your app need to be sped up. Hope this is helpful! ----Scott.
