In Translate5 I have configured four TermTaggers:

runtimeOptions.termTagger.url.default[] = "http://localhost:9001"
runtimeOptions.termTagger.url.default[] = "http://localhost:9002"
runtimeOptions.termTagger.url.default[] = "http://localhost:9003"
runtimeOptions.termTagger.url.default[] = "http://localhost:9004"

confirmed by a debug output of the config array.

Debug output in editor_Plugins_TermTagger_Worker_TermTaggerImport around the tagterms method shows, that only the taggers 9002 - 9004 are used. The tagger on 9001 does not get a request!

See also TRANSLATE-497 because of parallel instead sequential processing.
