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.
yea. download it natively on your NackeredBook Air first then copy it to the virtual machine.
Is it true that Apple slow down the download of certain specific files when running Windows 7 on a virtual box?
I use Fusion (VMWare) all the time with J-Link. Performance is the same as on the windows host. So there is a solution: Use J-Link or J-Trace from Segger.
You mean that file downloads on Internet will magically be faster if using Seggar JTAG-interfaces?
It worked! Thank you!! Apple download is much faster than downloading through virtual box.
In general, doing anything natively is going to be faster than doing it through any sort of virtualisation/emulation - other things being equal...
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 "faked" driver with a big buffer of shared memory to communicate directly with a driver in the host machine, then everything will go very slowly.
So a good virtual machine implementation really should be able to run the virtual network interfaces at "full link speed", being able to keep a 1gbit physical link glowing.
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.
