So, that shouldn't be taxing your memory too much.

I couldn't reproduce your problem. I ran your program verbatim on my windows system running Vista64, (AS)5.10.1 and IO::Compress:2.060 and on files 65/210MB and 80/600MB and they both took roughly 5 seconds to disk and 3 seconds in memory.

Does the same problem exhibit on all files when decompressed to memory or is it confined to one particular file?

One possibility (mentioned by Corion) is indicate by excessive page faults for the process(*). If the process shows a page fault delta greater than double digits per second, you have probably encountered the malloc problem. But if that were the case, I would have expected to be able to reproduce it here on my standard AS install.

(*You'll need Process Explorer or work out how to use perfmon.exe to find this information.)

    [hippo]: GDPR applies to everyone but there is an exception for individuals keeping records of their own personal activities.
    [hippo]: The full monty
    [hippo]: It is, of course, an utter mess.
    [Corion]: marto: GDPR is focused on businesses and business-like entities (like my Perl club), but you mostly have to have a set of (technically enforced) rules when to delete data, and also an overview of what kinds of data you collect and why.
    [choroba]: The basic message was "The regulations remain the same, what changed is the fines"
    [Discipulus]: here we are blatantly uncompliant..
    [marto]: hippo yes, but the list of exceptions (Section 17 IIRC) is open to interpretation
    [Corion]: For small businesses, there isn't much to do IMO, as long as you don't outsource anything and don't employ third parties (like Google Analytics, or mailing list services/ advertising services etc.)
    [Discipulus]: hippo you'll need a malox after each paragraph..
    [marto]: Corion so say a mailman mailing list? This falls under exceptions, there's nothing private stored on a public mailing (well, discussion) list, rather than a marketing list
