yes it can be faster by following steps :
you can find the file in pub static by following command
find pub/static -iname yourjsfile.js
.htaccess in pub/static send the missing files to pub/static.php with parameter resource and pub/static.php file creates an StaticResource for the file if available and deploy that.
Note: this only works with apache mod_rewrite
For Nginx you need to configure the same via nginx.conf.sample
