Slow to load when internet connection is on

[lluisfortes1]

I'm using RBioFormats v0.0.57 and rJava v0.9-13.
After last update of RBioFormats, thanks to add the possibility to load without internet connection.
A pair of days ago, I noticed the package is too slow to load in a fresh session.
Performing a microbenchmark, time consumed to load the package is dependent if there is an internet connection.
When my computer is offline, the loading time is around 1.32 seconds. On the other hand, when my computer is connected to internet, the loading time increase to 61 seconds!!
I noticed it, when performing a devtools::check() job to a package I'm developing, because I have to wait around 23 minutes to success. A pair of weeks ago, it was around 2 minutes. Posted in stackoverflow

I cannot reproduce the same behaviour. Nowadays, it's loading semi-instantly. Maybe it was related to my developing environment. I've moved to clean start RStudio without restoring source files...etc from previous session
