   private static Map<String, Id> profileIdByName = new Map<String, Id>();
    
   public static Id getProfileIdByName(String profileName) {
        
        if (!String.isBlank(profileName)) {
        
          if (profileIdByName.containsKey(profileName)) {
                return profileIdByName.get(profileName);
            }
         else{        
            for(Profile pfInstance:[SELECT Name,Id FROM profile

                profileIdByName.put(pfInstance.Name,pfInstance.Id);            
            } 
            
            return profileIdByName.get(profileName);
          }               
       }
