Rebuild time with react on refresh

Hi. Each time I update a client file it takes a very long time to refresh.
It seems to come from the templating-compiler plugin.
Any idea how I could speed-up this ?
I’m on meteor 1.4.2 on macos (macbookpro mid 2010, ssd, 8Go ram)

├─ plugin templating-compiler…117,813 ms (1)
| │ │ │ ├─ wrapped.fs.readFileSync 117,431 ms (394)
| │ │ │ └─ other plugin templating-compiler 382 ms

Tell me if you need more details to help.

Thanks
