slow load speed of data from mysqldump
Take these some points in your consideration they may help you in case of generating the dump and restoring it. 


Use Extended inserts in dumps.
Dump with --tab format so you can use mysqlimport, which is faster than mysql &lt; dumpfile.
Import with multiple threads, one for each table.
Use a different database engine if possible. importing into a heavily transactional engine like innodb is awfully slow. Inserting into a non-transactional engine like MyISAM is much much faster.
Turn off foreign key checks and turn on auto-commit.
If you are importing to innodb the single most effective thing you can do is to put innodb_flush_log_at_trx_commit = 2 in your my.cnf, temporarily while the import is running. you can put it back to 1 if you need ACID
