Version: unspecified (using KDE 4.7.2) OS: Linux I was on openSUSE 11.4 and now upgraded to 12.1 (kde 4.7.2), and I can't work anymore as simply everything is extremely slow. kontact/kmail eats cpu+ram together with all that stuff that it suddenly needs (nepomuk,akonadi,virtuoso). This is a 6-core cpu with 8GB RAM, and it's so slow even Windows would run much faster. What can I do to get a working system again? top - 09:08:35 up 2 days, 20:18, 90 users, load average: 2.13, 2.26, 1.92 Tasks: 333 total, 4 running, 329 sleeping, 0 stopped, 0 zombie Cpu(s): 22.9%us, 2.3%sy, 0.0%ni, 74.2%id, 0.6%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 8190476k total, 8020636k used, 169840k free, 3924k buffers Swap: 4554296k total, 2243160k used, 2311136k free, 1184732k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 5820 zmi 20 0 1505m 1.4g 652 S 11 17.5 50:22.01 dbus-daemon 6055 zmi 39 19 1462m 1.2g 3068 S 0 14.9 389:41.14 virtuoso-t 2821 root 20 0 2126m 979m 2052 R 9 12.3 429:58.10 Xorg 956 zmi 20 0 2572m 598m 11m S 1 7.5 37:28.38 kontact 26288 zmi 20 0 1251m 504m 17m R 10 6.3 452:59.06 firefox-bin 7580 zmi 20 0 861m 425m 6084 R 100 5.3 47:53.34 akonadi_nepomuk 7782 zmi 39 19 541m 223m 4496 S 0 2.8 34:52.43 nepomukservices 7570 zmi 20 0 986m 200m 6020 S 0 2.5 292:48.31 akonadi_imap_re 6010 zmi 20 0 3143m 109m 2648 S 6 1.4 188:15.30 mysqld 7413 zmi 20 0 4551m 84m 6352 S 0 1.1 9:55.22 soffice.bin 7568 zmi 20 0 721m 82m 6960 S 4 1.0 19:41.48 akonadi_imap_re 6048 zmi 20 0 547m 78m 6824 S 4 1.0 31:24.09 konsole 6041 zmi 39 19 2181m 67m 4712 S 0 0.8 95:43.41 nepomukservices 6006 zmi 20 0 2674m 37m 2656 S 1 0.5 113:41.39 akonadiserver 5990 zmi 20 0 1219m 34m 9.9m S 2 0.4 35:28.09 plasma-desktop 7564 zmi 20 0 583m 26m 6156 S 0 0.3 32:01.28 akonadi_imap_re 7565 zmi 20 0 584m 24m 6048 S 0 0.3 2:50.26 akonadi_imap_re 6033 zmi 20 0 1612m 24m 6192 S 0 0.3 22:38.10 krunner 7569 zmi 20 0 665m 23m 8044 S 0 0.3 2:52.27 akonadi_imap_re 7561 zmi 20 0 578m 22m 7192 S 0 0.3 7:59.94 akonadi_imap_re 7567 zmi 20 0 695m 21m 7836 S 0 0.3 1:18.74 akonadi_imap_re 5872 zmi 20 0 579m 20m 6224 S 1 0.3 87:06.92 kwin 7560 zmi 20 0 579m 20m 7268 S 0 0.3 1:21.64 akonadi_imap_re 7563 zmi 20 0 670m 20m 7416 S 2 0.3 36:03.15 akonadi_imap_re Reproducible: Always Steps to Reproduce: Start KDE with kmail and firefox - try to work. All was good in kde 4.4. I've also had a very hard time upgrading kmail, but there have been thousands of complaints to that so I guess you know it already ;-) Expected Results: A quick and working system - at least quicker than Windows, please!
If this is happening with KDE 5, please leave a comment.
