one table or separate into different tables for best mysql query performance? -


i learnt how develop simple php website mysql database. user can create post in 3 different categories. (columns in each of these tables same)

so know whether save posts in 1 table (9.000 results) or separate them 3 tables (3000 results each ) , use union retrieve found results in search result page?

this fundamental step database design. please advice!

use single table. standards of sql, 9000 rows not large table.

there numerous reasons why want 1 table. here few:

  • you can have foreign key references single table.
  • it easier maintain.
  • performance better, because have fewer partially filled pages.

you want create appropriate indexes on table, table.

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
