It's simple to load treeview nodes from table using a recursive function, but it takes a long time for huge data.  

I have a table with these fields: ***id, title, parentid*** : that keeps treeview nodes in N level. 

This table has more than 70000 rows. When i fill treeview from this table it take a long time (about 9 mins) for completion. 

Is there a beter solution to increase loading speed?
