    Did some API request size and time comparisons for various pagesizes 
against a large template collection (more than 4000 templates across 30+ zones);
    
    Page Size | API response size (KB) | Time (ms)                              
        
    --------- | ---------------------- | ---------                              
        
    20 | 15.8 | 360                                                             
        
    100 | 77.1 | 366                                                            
        
    150 | 117 | 448                                                             
                                                                                
                              
    200 | 157 | 408                                                             
        
    250 | 199 | 440                                                             
        
    500 | 402 | 791
    
    Based on this data, on the lowest side pagesize of 100 seems alright for 
the time taken vs the payload size, but has more risk on a lower reduced list 
size (not enough to render a scroll); on the higher side pagesize of 200-250 
seems alright considering roughly similar time.
