Hi&nbsp;Jean-marine,&nbsp;  
&nbsp;&nbsp;  
&nbsp;You&nbsp;need&nbsp;to&nbsp;set&nbsp;the&nbsp;ThreadingMode&nbsp;to&nbsp;MultiThreaded,&nbsp;and&nbsp;then&nbsp;need&nbsp;to&nbsp;add&nbsp;the&nbsp;lock&nbsp;pattern&nbsp;when&nbsp;you&nbsp;try&nbsp;to&nbsp;update&nbsp;overlay&nbsp;(such&nbsp;as&nbsp;change&nbsp;style,&nbsp;add&nbsp;or&nbsp;remove&nbsp;features).&nbsp;  
&nbsp;&nbsp;  
&nbsp;Here&nbsp;is&nbsp;the&nbsp;documentation&nbsp;link&nbsp;for&nbsp;that:&nbsp;[wiki.thinkgeo.com/wiki/ThinkGeo.MapSuite.DesktopEdition.MapThreadingMode](http://wiki.thinkgeo.com/wiki/ThinkGeo.MapSuite.DesktopEdition.MapThreadingMode)&nbsp;  
&nbsp;&nbsp;  
&nbsp;And&nbsp;this&nbsp;link&nbsp;should&nbsp;be&nbsp;helpful&nbsp;also:&nbsp;[gis.thinkgeo.com/tabid/143/afv/topic/aff/42/aft/9172/Default.aspx](http://gis.thinkgeo.com/tabid/143/afv/topic/aff/42/aft/9172/Default.aspx)&nbsp;  
&nbsp;&nbsp;  
&nbsp;Regards,&nbsp;  
&nbsp;&nbsp;

&nbsp;&nbsp;  
&nbsp;I&nbsp;remember&nbsp;you&nbsp;read&nbsp;data&nbsp;from&nbsp;database,&nbsp;because&nbsp;we&nbsp;cannot&nbsp;control&nbsp;network&nbsp;speed,&nbsp;I&nbsp;think&nbsp;this&nbsp;step&nbsp;should&nbsp;be&nbsp;your&nbsp;slowest&nbsp;part,&nbsp;I&nbsp;am&nbsp;not&nbsp;sure&nbsp;whether&nbsp;MultiThreaded&nbsp;mode&nbsp;can&nbsp;help&nbsp;you&nbsp;improve&nbsp;your&nbsp;enhancement,&nbsp;I&nbsp;think&nbsp;you&nbsp;can&nbsp;have&nbsp;a&nbsp;quickly&nbsp;try&nbsp;for&nbsp;multi-thread,&nbsp;because&nbsp;change&nbsp;render&nbsp;mode&nbsp;really&nbsp;easy.&nbsp;
