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.

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).
