take too much time to load page

is their any way to handle this

Answer 1

它解决了在计数记录时num_rows()需要20秒 ，而$this->db->select('COUNT(*) as count')与get（）-> row（）只需0.63秒

Answer 2

Generally the speed of your queries are based on indexes and references. I would suggest that you check that first.

You can use the 'Explain' statement to get a better idea as to how to optimize your query. Here is more information directly from the MySQL site.

I would also highly recommend turning on 'profiler' for CI to determine where the bottle neck actually is.

$this->output->enable_profiler(TRUE);

Thirdly if I am not able to get any additional information back based on your profiler I would alternately recommend you using jQuery datatables in conjunction with CI, its server side processing can handle millions of rows within a short time. It will only load the page that is currently active to make things a lot more simpler and easier on the users end.
