What parameters are You use for Talend tMySQLOutput? What MySQL settings?
It could not be faster then INFILE, but still really depend from settings.

You can post Your question on TelndForge forum with screen short of Job components, will try to help

For example one of my regular Talend-MySQL Jobs (billing prepare) - transfer from->to mysql 2M of records, 400Mb, it take 6-15 minutes depending from servers (we have 2 configuration)
