Looking through the code, I've found out there are two implementations of hashing function. Swapping happens only when the fast one is in use.
-- Excessive swapping during hash https://bugs.launchpad.net/bugs/376896 You received this bug notification because you are a member of LinuxDC++ Team, which is subscribed to LinuxDC++. Status in Linux DC++: New Bug description: There is a reproducable problem in linuxdcpp (or maybe it is the kernel/libc?), where hashing a large file causes excessive swapping to occur, while memory usage is far from 100%. I've seen this on at least two different machines, both working under gentoo amd64 and both using 2.6.29.2 kernel. Steps to reproduce: 1. Start X/GNOME/KDE, some programs in the background to give system something to swap 2. Start hashing some _big_ files (say, 2GIG and more on a system with 4GiGs of RAM) 3. See swapping to occur I don't know whether thisi is a kernel or stdlib or linuxdcpp issue, but I only see such swapping with linuxdcpp Here is a "vmstat 2" output during hashing of two big files in the attachment _______________________________________________ Mailing list: https://launchpad.net/~linuxdcpp-team Post to : [email protected] Unsubscribe : https://launchpad.net/~linuxdcpp-team More help : https://help.launchpad.net/ListHelp
