I am using Web RStudio by accessing remote to my own Ubuntu 14.04 LTS server (RStudio Server). I have no problem of using this program after installing several packages from User Library until this happens. After I installed additional packages, KoNLP, tm, etc..., RStudio itself has become laggy. I don't know why RStudio is very slow. Please let me know what is the cause of this situation.
Please excuse my English since it is not my native language.
