My Grunt watch task is experiencing significant delays between detecting a file change and starting to work.
Output similar to the following is frequently seen:
>> File "src/static/app/brandManager/addChannel.html" changed.
Running "html2js:main" (html2js) task
Successfully converted 13 html templates to js.
Done, without errors.

Although the actual work only took 597ms, the total task ran for 14.469s.
Below is the relevant snippet from my Gruntfile:
src: {
js: ['src/static/app/**/*.js', '!src/static/app/**/*.spec.js'],
},
watch: {
js: {
files: ['<%= src.js %>'],
tasks: ['fileblocks','newer:jshint:all'],
options: {
livereload: false
}
},
livereload: {
options: {
livereload: '<%= connect.options.livereload %>'
},
files: [
'<%= src.html %>',
'.tmp/styles/{,*/}*.css',
'<%= src.assets %>'
]
}
}
Regardless of the watch target invoked, there is consistently a delay of varying lengths, ranging from 5s to as long as 60s (though typically around 15-20s).
This delay is negatively impacting my workflow. How can I troubleshoot the cause?
Edit:
The number of files being watched is not insignificant but also not extensive:
--- static/app ‹master› find -f . | wc -l
>> 51
