Re^2: Parallel::ForkManager and vars from the parent script - are they accessible? (or do I need inter process communication?)

IPC::Shareable is kind of slow, but it may not matter for your data. If you run into trouble with it, MLDBM::Sync is an easy way to share a hash on disk.

Slow!? I thought it is fast, because everything is held in memory... (the on-disk approach is what I am trying to circumnavigate here...)	[reply]

It's slow because it has to serialize and deserialize the entire hash through Storable every time you want to read or write it to/from the shared memory slot. It's fine for a small hash, but a large one will get slow.	[reply]
