[racket-dev] Any notion of ".jar" files for Racket?

It gets much faster once the files are in OS caches, which helps with 
successive invocations of the command-line tools.

The uncached accesses going over NFS could be especially painful, such 
as if you are running a copy of DrRacket from a slow NFS home dir.

(I feel for anyone who has to use NFS nowadays, such as some university 
communal computers are no doubt still set up to use.  NFS and AFS were 
great 20 years ago, at least when the servers and the network were 
non-flaky and not oversaturated.  Today, we usually want to be using our 
own computer with a local copy of files (or a USB flash drive with 
communal computers), not having every file access go out to centralized 
server.  Popular SCM systems like Git and Subversion are good ways to 
replicate most of our files among systems, and permit disconnected 
operation in between.  I'd still offer students an NFS dir they're free 
to use, especially new students working from lab computers, but 
encourage them to use their own local storage for most things.  And I'd 
provide a big Git server with private accounts, which students may use 
for coursework if they wish.)
