Mac OS X 10.10 Yosemite, SAV Mac 9.2.2, and You

bobcook

Hey everyone,

We released version 9.2.2 to all Home Edition endpoints earlier today, this version contains the latest updates and is compatible with Mac OS X 10.10. Although the previous version (9.1.5) was also compatible, this update brings the latest improvements and refinements.

We also posted a new installer to our website today as well. Visit www.sophos.com if you need a copy.

    I did notice that the CPU usage of the SophosWebIntelligence process rises to more than 50% when running speedtest.net's web app.  I'm not noticed such high usage before; but given the large number of complete requests/responses generated by this test I think this is in hindsight understandable.  If this were to rise any further I would expect to see a degredation in download performance.

    I'm wondering whether your new Yosemite system is indexing itself, or doing something else CPU intensive?  Or, perhaps your machine isn't as powerful as the test system I used.  I would suggest you run another speedtest but this time check out your system CPU usage in Activity Monitor; in particular monitor the CPU usage of the SophosWebIntelligence and SophosScanD processes.

    I would speculate that the high CPU usage you'll see from speedtest.net represents a worst-case for CPU consumption by these two Sophos processes.  I am curious to know whether you can download a single large file at full speed irrespective of whether web protection is enabled.

    Hi,

    I tried numerous Speedtests, and the thing which stands out, is with the Sophos AV Web Protection modules on, there is a high CPU load of around 50-55% of the "Safari Networking" deamon. Flash is around 45%, rest nothing worthwhile.

    When the modules are off, the Flash deamon is around 33%, and de Safari Networking deamon non-existend.

    So there is a much higher CPU load from the Safari Networking deamon, with the Web Protection modules on.

    However: the same issue persists when using Google Chrome. Exactly the same (speedcap). Under Activity Monitor other deamons show up (mostly Chrome Helper), but the CPU load is around 35%. Same speedcap as with Safari.

    I'm looking for an App to measure troughput on my local (gigabit)network, to check the transfer of a large file, as you mentioned.

    Btw, it is not the system itself, when not doing any speedtests, the CPU load is virtually 0% (1 maybe...). No indexing etc whatsoever.
