Current sql import limit is (Max: 2,048KiB). I think it is better if user can specify this value. At least this feature should enable when user use a local server.
This limit depends on the server, see http://docs.phpmyadmin.net/en/latest/faq.html?highlight=upload#i-cannot-upload-big-dump-files-memory-http-or-timeout-problems
