I thought I would share my success with all of you. By making a userimg.jl in the julia folder containing the following and building the sysimg with the command bellow, the load time of of PyPlot's can be reduced by a factor of 3. >julia -e "tic(); using PyPlot; toc()" INFO: Loading help data... elapsed time: 21.096362371 seconds With custom userimg.jl >julia -e "tic(); using PyPlot; toc()" INFO: Loading help data... elapsed time: 7.611489099 seconds
My userimg.jl contains the following: ## userimg.jl require("PyCall") require("Color") Command for building the sysimg bin\julia.exe share\julia\build_sysimg.jl --force C:\your_path_here\Julia- 0.3.7\lib\julia\sys native userimg.jl If `require("PyPlot")` is added to the userimg.jl the sysimg is not usable. If any of you have ideas for further reducing the load time of PyPlot it would be greatly appreciated.
