anyone expereinced very slow download speed of MDK472_A.exe to
Macbook Air through virtual box running window 7? Any way to make it
faster? thanks.

But some emulations are very light-weight - for virtual machines
it really is important that the virtual machine has some form of
drivers that can interface directly with the host machine. If the
virtual machine is emulating real hardware down to the register level
instead of just having a &amp;quot;faked&amp;quot; driver with a big buffer of shared
memory to communicate directly with a driver in the host machine,
then everything will go very slowly.&lt;/p&gt;

&lt;p&gt;
So a good virtual machine implementation really should be able to
run the virtual network interfaces at &amp;quot;full link speed&amp;quot;, being able
to keep a 1gbit physical link glowing.&lt;/p&gt;

&lt;p&gt;
Next thing is that most operating systems are starting to have
native virtualization (in some part needed for their multi-core
support) which means that virtual machines and multiple programs
running natively will often see very little difference. But once more
- only if the virtual machine contains a good mapping layer with
replaced, custom, drivers.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: slow download through virtual box on macbook air</title><link>https://community.arm.com/thread/107257?ContentTypeID=1</link><pubDate>Mon, 02 Sep 2013 14:52:16 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:aeb8e69b-7a01-4fcd-a3c6-35485d5c9a62</guid><dc:creator>Andy Neil</dc:creator><description>&lt;p&gt;&lt;p&gt;
In general, doing anything natively is going to be faster than
doing it through any sort of virtualisation/emulation - other things
being equal...&lt;/p&gt;

It worked! Thank you!! Apple download is much faster than
downloading through virtual box.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: slow download through virtual box on macbook air</title><link>https://community.arm.com/thread/107254?ContentTypeID=1</link><pubDate>Sun, 01 Sep 2013 13:08:18 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:c7b4b81c-3022-434a-bca1-26c5a533b7f0</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
You mean that file downloads on Internet will magically be faster
if using Seggar JTAG-interfaces?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: slow download through virtual box on macbook air</title><link>https://community.arm.com/thread/81414?ContentTypeID=1</link><pubDate>Sun, 01 Sep 2013 11:34:20 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:aaf9c675-6c69-428d-b407-381e9d2e3bf9</guid><dc:creator>Experienced Developer</dc:creator><description>&lt;p&gt;&lt;p&gt;
I use Fusion (VMWare) all the time with J-Link. Performance is
the&lt;br /&gt;
same as on the windows host.&lt;br /&gt;
So there is a solution: Use J-Link or J-Trace from Segger.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: slow download through virtual box on macbook air</title><link>https://community.arm.com/thread/62232?ContentTypeID=1</link><pubDate>Sun, 01 Sep 2013 05:18:03 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:93cd0013-47e1-4259-8f1d-a3727e944624</guid><dc:creator>jambi jambi</dc:creator><description>&lt;p&gt;&lt;p&gt;
yea. download it natively on your NackeredBook Air first then copy
it to the virtual machine.&lt;/p&gt;

&lt;p&gt;
Is it true that Apple slow down the download of certain specific
files when running Windows 7 on a virtual box?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
