Emilio, I do see quite an improvement as 1.6 is something in the ballpark of 40% faster for me. Ext4/fdatasync(?) help too as the rest of the system stays fairly responsive.
Unfortunately it still means counting startup and feed update times in minutes on my setup. Have a look at the time stamps of the attachment. The main window showed up roughly 2min in and then it stayed mostly grey (compiz) for another 16min until all feeds where updated and drive activity went down. Add 20s for my reaction time to close it and the total is real 18m53.812s user 0m0.952s sys 0m1.104s 1344 fdatasyncs ~39MiB written to the drive (/proc/diskstat) With the patch and LIFEREA_SYNCHRONOUS=0: real 0m37.556s user 0m0.704s sys 0m0.772s 0 fdatasyncs, a handful of fsyncs ~1.49 MiB written to the drive (/proc/diskstat) This is with a fresh profile, all the default feeds and 270 new messages. And again, this drive is slow, particularly for random-like I/O. I'm sure the majority of disks does better. This is what I did: rm -rf .liferea_1.4 .liferea_1.6 a) unset LIFEREA_SYNCHRONOUS b) export LIFEREA_SYNCHRONOUS=0 sync time strace -e fsync,fdatasync -Ff -tT liferea 2>&1 | tee /tmp/strace_liferea_1.6.0~rc6-1ubuntu1.txt Where "/tmp" is a ram disk to take logging out of the picture. ** Attachment added: "strace_liferea-1.6.0~rc6-1ubuntu1.txt" http://launchpadlibrarian.net/29038504/strace_liferea-1.6.0%7Erc6-1ubuntu1.txt -- Liferea stalling, uses excessive number of fsyncs https://bugs.launchpad.net/bugs/290666 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
