The bottleneck can be at database level, web server level, at php level, or in your php script itself. Try to identify at which level is the slowness.

If all web pages at your web server are s-l-o-w, then you should check your web server configuration.

If other pages (such as html, perl-cgi etc) are fast, but only php pages are slow, then check what may be wrong with php.

If other php pages are fast and this particular page is slow, then check the php code.

I am not a database expert, so can't say much about it. Particularly, check if you can optimize the query that you are using in your php script.

If number of records in the tables are huge, and your query results in output of say 1000 records, then transferring that much data from web server to client (browser) may be slow.

mysqlnd_ms_match_wild - Finds whether a table name matches a wildcard pattern or not

SYNOPSIS
bool mysqlnd_ms_match_wild (string $table_name, string $wildcard) DESCRIPTION
Finds whether a table name matches a wildcard pattern or not. This function is not of much practical relevance with PECL mysqlnd_ms 1.1.0 because the plugin does not support MySQL replication table filtering yet. PARAMETERS
o $table_name - The table name to check if it is matched by the wildcard. o $wildcard - The wildcard pattern to check against the table name. The wildcard pattern supports the same placeholders as MySQL replication filters do. MySQL replication filters can be configured by using the MySQL Server configuration options --replicate-wild-do-table and --replicate-wild-do-db. Please, consult the MySQL Reference Manual to learn more about this MySQL Server feature. The sup- ported placeholders are: o % - zero or more literals o _ - one literal Placeholders can be escaped using . RETURN VALUES
Returns TRUE table_name is matched by wildcard. Otherwise, returns FALSE EXAMPLES
Example #1 mysqlnd_ms_match_wild(3) example <?php var_dump(mysqlnd_ms_match_wild("schema_name.table_name", "schema%")); var_dump(mysqlnd_ms_match_wild("abc", "_")); var_dump(mysqlnd_ms_match_wild("table1", "table_")); var_dump(mysqlnd_ms_match_wild("asia_customers", "%customers")); var_dump(mysqlnd_ms_match_wild("funny%table","funny\%table")); var_dump(mysqlnd_ms_match_wild("funnytable", "funny%table")); ?> The above example will output: bool(true) bool(false) bool(true) bool(true) bool(true) bool(true) PHP Documentation Group MYSQLND_MS_MATCH_WILD(3)
