You also lose all that efficiency when you start to read a lot of data structures in perl, because reading data ca n increase the reference counters, thus a write actually happens in the background, causing the operating system to copy the pages.

So, don't assume stuff is memory unfriendly. Measure it. In your context, where it matters.

Also, starting a new perl interpreter takes about 0.017s "cold" on my machine, and 0.002s when cached. Compared to a 1 minute run time of a worker thread, that's like 0.03% (cold) or 0.003% (warm) - nothing to worry about.

    [RonW]: Sounds like some system my employer has "It does exactly what we need it to do and can't afford to risk anything we can't prove is 100% compatible"
    [marto]: choroba sounds interesting
    [RonW]: james28909 Why not write a Perl program to do the task?
    [choroba]: RonW Yes, but then, one day, they needed to switch from FTP to SFTP, and... but I can't give the whole talk away here :)
    [RonW]: Tunnel FTP through stunnel?
