JS:concat-processing gigant time required

See original GitHub issue

Hi, guys. First of all I really want to say thank you for great tool. I’m happy to use it, but now I have some unpleasant issue. js:concat-processing required about 4-5 min. Mb you have some solution or any ideas about the reason of this trouble.

Please find below my tars-config file
