Some real-world comparisons in human units: https://gist.github.com/hellerbarde/2843375 https://www.pcgamer.com/heres-a-neat-trick-for-understanding-how-long-computer-processes-take/ If fetching the next instruction from the next location in L1 cache took 1 second, getting it from main memory would take over a minute and a half. Getting it from an SSD, a weekend. Getting it from a hard disk, about 4 months. -- Liam Proven – Profile: https://about.me/liamproven Email: lpro...@cix.co.uk – gMail/gTalk/gHangouts: lpro...@gmail.com Twitter/Facebook/LinkedIn/Flickr: lproven – Skype: liamproven UK: +44 7939-087884 – ČR (+ WhatsApp/Telegram/Signal): +420 702 829 053 _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
