Dear,
It depends a bit on what the activity is at that moment. 26,5% does not seem that high. But without knowing if there is scanning going or not, it is difficult to say.
There are other jobs also running in the background, like report calculations, CDR, Asset Radar, Lsagent, etc One of the things we would check is if the database is in good shape. Growth of the database, can cause longer calculation and more CPU usage.
If any doubt you can contact Lansweeper Support.
