backup - Speeding up mysql dumps and imports -

-

are there documented techniques speeding mysql dumps , imports?

this include my.cnf settings, using ramdisks, etc.

looking documented techniques, preferably benchmarks showing potential speed-up.

http://www.maatkit.org/ has mk-parallel-dump , mk-parallel-restore

if you’ve been wishing multi-threaded mysqldump, wish no more. tool dumps mysql tables in parallel. smarter mysqldump can either act wrapper mysqldump (with sensible default behavior) or wrapper around select outfile. designed high-performance applications on large data sizes, speed matters lot. takes advantage of multiple cpus , disks dump data faster.

there various potential options in mysqldump such not making indexes while dump being imported - instead doing them en-mass on completion.
