    Physical Memory Usage - sFTP

    Hello,

    Why does the Physical Memory Usage go to 100% when customers are downloading files trough FTP?
    I know it takes CPU, I/O etc, but I cannot see why memory usage should go up. Is files cached while they are downloaded?

    Customers are worried that their site will go down while they take backup of their site trough FTP.
    But my guess is that its just cached as this feature is really wanted:
    Remove "Cached" memory from Physical Memory usage stats
    https://cloudlinux.uservoice.com/forums/269295-general/suggestions/34497679-remove-cached-memory-from-physical-memory-usage
    In cPanel graphs (e.g. in the sidebar), "Physical Memory Usage" contains "Cached" memory in its calculation - as a system administrator this makes sense because in fact "Cached" memory is used but can get freed up in the system needs it. However, seen from a customer perspective that isn't very technical, the "Cached" memory concept doesn't make much sense because even if no processes run on my account, it could still cause a very high usage in the graph, something like this: https://snaps.hcdn.dk/aiyNRHmG99NmcdEFsnQ9OSr548yLWpTtcVeIvqBDey.png The graph says the account is using 95.88% of the memory for the account and gives a warning. This triggers tickets (despite having a KB post that explains that they most likely shouldn't worry) - for this particular account, only 5 megabyte of the 1920 megabyte was actually in use. I think this has to be changed (or give us an option to include "Cached" memory or not - it will greatly lower confusion for customers and tickets towards providers :-)
