Been using Julia for \< 1 day, so pardon any dumb questions…  
I installed the Plots package (`using Pkg; pkg.Add("Plots")`).  
(1) Then the first time I did `using Plots`, I saw "`[Info: Precompiling Plots [91a5bcdd-55d7-5caf-9e0b-520d859cae80]``" for about 15-20 seconds. (2) Further, when I used `plot(x, y)` for the first time, it took about 4 seconds to plot and faster thereafter.

Q1: Is (2) just an effect of JIT? Also is ~4 seconds really the time it’ll take the first time or have I installed something incorrectly?  
Q2: What’s the reason for (2) and is the time it took normal?  
(I use Ubuntu 16.04 w/ 16GB Intel Core™ i7-6700 CPU @ 3.40GHz × 🕶

Many parts of the Plots package are precompiled the first time you enter `using Plots`. This work takes a handful of seconds, as you experienced. For similar reasons, when you start a Julia session and make an initial plot there is a few seconds’ delay. Subsequent plots come up quickly.
