Presenting 10-fold increases in speed of new IMAP gateway and the doubling of Enterprise MySQL performance

At FOSDEM 2011 (5-6 February, Brussels), Zarafa, the leading European provider of open source groupware and collaboration will present its new Zarafa Collaboration Platform (ZCP) 7.0.0 beta2 with a new, faster IMAP gateway and share how Enterprise MySQL performance can be doubled.

Joint Zarafa Community Efforts Results in New IMAP gateway
Community contributions and valuable feedback has enabled Zarafa to launch a new ZCP IMAP gateway that also helps ZCP to benefit from 10-fold increases in speed and new possible security enhancements. Better compatibility for users with generic IMAP clients, like Mac Mail and Thunderbird, has been realized due to a new configuration option to store more message information.

Guy van Sanden, open source consultant at the Belgian system integrator Open future says: “Besides Zarafa’s recent decision to make the bug tracking system public, it thrills me that, from now on, all PGP/mime emails and s/mime encrypted mails will be supported and all message headers can be retrieved. The test results are promising”.

Doubling MySQL Performance Well Received by Open Source Opinion Leaders
On Saturday, 5th of February at 2pm in the MySQL Developer Room (H.2213), Steve Hardy, CTO at Zarafa, will present the results of research3 into the I/O performance of MySQL in typical enterprise setups. This new development can improve total disk throughput by more than 100% in certain cases.

Mark Callaghan of Facebook says: ”This is very interesting. My workload has too much concurrency already so I am most interested in the change to make records_in_range do less IO”.

The interaction with leading technical IO architects and the acceptance of this talk at the FOSDEM MySQL track is in line with Zarafa´s determination to display its commitment to state of the art thought leadership in groupware I/O R&D.

3 Research into the I/O performance of MySQL in typical enterprise setups
Tests have shown that InnoDB is not using traditional spindle-based I/O subsystems to their maximum potential while doing OLTP workloads with I/O-bound queries. Pages are requested sequentially from the disk system instead of asynchronously, even when using MySQL 5.5's native Aynchronous I/O support. The presentation shows the advantages of implementing a prefetch mechanism which can result in large gains in I/O performance. For more information about the InnoDB prefetch improvement see this mailinglist post: http://lists.mysql.com/internals/38126.

Qt/KDE: Qt5 in Debian and Slackware, QtCreator on Android, KDE Discover, and Plasma's 10th Anniversary

  • moving Qt 4 from Debian testing (aka Buster): some statistics, update II
    We started filing bugs around September 9. That means roughly 32 weeks which gives us around 5.65 packages fixed per week, aka 0.85 packages per day. Obviously not as good as we started (remaining bugs tend to be more complicated), but still quite good.
  • [Slackware] Plasma5 – April 18 edition for Slackware
    The KDE-5_18.04 release of ‘ktown‘ for Slackware-current offers the latest KDE Frameworks (5.45.0), Plasma (5.12.4) and Applications (18.04.0). The Qt5 was upgraded to 5.9.5. Read the README file for more details and for installation/upgrade instructions. Enjoy the latest Plasma 5 desktop environment.
  • Perfect Debugging Experience with QtCreator on Android
    While I was working on a yet-to-be-announced super secret and cool Qt on Android project, I had to do a lot of debugging. This way I found that debugging Qt apps on Android using QtCreator was ok, but it had some issues, which was kinda frustrating.
  • Discover – Easily Install Software on KDE Neon Desktop
    KDE Discover is an Open Source GUI app installer that comes packaged with KDE Neon. It was particularly built from the ground up to be compatible with other modern Linux distros with emphasis on beauty and convenience. KDE Discover was also designed to allow for an intuitive User Experience as it features a clean and clear layout with a high readability value which makes it easy to browse, search for, install, and uninstall applications.
  • Almost 10 years of Plasma-Desktop
    Last week I was at work and start to listen my boss said: “We need to show this to our director”. So I went to my coworker table to see what was happening. So they were using Gource to make a video about the git history of the project. Gource is a software version control visualization tool. So that triggered in my mind some memories about a friend talking about Python and showing how the project as grow in this past years, but I never discovered about the tool that made that amazing video. So well, I started to make some Gource videos, and because my love about KDE Community, why not make one about it?

GNOME: Getting Real GNOME Back in Ubuntu 18.04, Bug Fix for Memory Leak

  • Getting Real GNOME Back in Ubuntu 18.04 [Quick Tip]

  • The Infamous GNOME Shell Memory Leak
    at this point, I think it’s safe to assume that many of you already heard of a memory leak that was plaguing GNOME Shell. Well, as of yesterday, the two GitLab’s MRs that help fixing that issue were merged, and will be available in the next GNOME version. The fixes are being considered for backporting to GNOME 3.28 – after making sure they work as expected and don’t break your computer.
  • The Big GNOME Shell Memory Leak Has Been Plugged, Might Be Backported To 3.28
    The widely talked about "GNOME Shell memory leak" causing excessive memory usage after a while with recent versions of GNOME has now been fully corrected. The changes are currently staged in Git for what will become GNOME 3.30 but might also be backported to 3.28. Well known GNOME developer Georges Stavracas has provided an update on the matter and confirmed that the issue stems from GJS - the GNOME JavaScript component - with the garbage collection process not being fired off as it should.
