First page loading speed is slow, is there a way to optimize it?

The first page has 15 SQL statements involving 7 data tables, loading speed is very slow (about 6 seconds, 2Mb bandwidth), is there any way to optimize it?

Reply to discussion (solution)

Direct SQL Analysis of DESC SELECT * from TabName ... Key fields are indexed to optimize the program's wording.

It seems to be optimizing your SQL. Index, Cache

2MB 6sec does not speak very slowly, just slightly slower
You can cache the first page query results to minimize the impact of database queries
If the effect is not obvious, it means that your page layout is unreasonable, too many nested

A lot of suggestions to see the relevant books, you will know.

Home cache, Dynamic Data, then use AJAX requests. Create the necessary indexes in addition
