In the example above, installing just the JLD package creates a <code>~/.julia</code> tree with 18673 files and directories and using 236M of space, almost 5% of a standard user's quota for <code>/home</code>. It's worth remembering that installing a lot of packages will consume a lot of space. | In the example above, installing just the JLD package creates a <code>~/.julia</code> tree with 18673 files and directories and using 236M of space, almost 5% of a standard user's quota for <code>/home</code>.

Because Julia precompiles packages (>1.6), a distributed Julia program can cause a spike of read/writes to ~/.julia/compiled. By configuring Julia to use (faster) storage you can avoid unnecessary slowdowns.

Preserving a julia installation can be done by compressing the contents of DEPOT_PATH. For example, if you decompress on fast local storage, but want to preserve on ~/project (compressed). However, note that the paths are hardcoded, so decompression should be done in an identically named path. | Preserving a julia installation can be done by compressing the contents of DEPOT_PATH.
