Should I get a more powerful license?

If your CPU usage is not spiking or becoming a bottleneck, then your existing license is okay for your server.
Our web server will only use what it needs. Increasing the usable CPU's may not improve the current performance.

A top command will reveal important information about how much resources different processes are taking on your server. (LSWS's process is called lshttpd, and LiteSpeed Web ADC's process is called lslbd) A couple of these outputs are useful for determining if your installation needs access to more cores:

  • %CPU - Generally LSWS's CPU usage is low. If LSWS's CPU usage starts climbing, and especially if it climbs while your overall load is low, it can indicate that LSWS is hitting a bottleneck and would benefit from access to more cores.
  • %wa - High I/O wait can also be an indicator that LSWS needs more worker processes (and thus access to more cores).
