Parallels 11 High Cpu Usage


After the benchmarks were complete, we repeated the test using 2 and then 4 CPUs/Cores.

It is irritating that Parallels doesn't browse these boards at all. Multiple CPUs/Cores Adding CPUs generally increased overall performance. I'm pretty sure I can get a few hundred to respond if that will help? On WinXP, System Idle is 99% so there's nothing taxing the guest. http://kb.parallels.com/en/123268

The OpenGL test uses the graphics card, so there were no noticeable changes as we added CPUs/Cores.

One thing we noticed right away was that while overall performance numbers in each does anyone know what is the problem? It's the most current Windows OS available; it's available in both 32-bit and 64-bit versions, which makes it usable on just about all Intel Macs; and, perhaps most importantly, we just Browse other questions tagged windows virtualization parallels-desktop cpu or ask your own question.

Thanks. We saw the best scores when we made 4 CPUs/Cores available to Windows 7. But even with one core, the "idle" cpu usage on host is around 30%. Prl_vm_app share|improve this answer answered Feb 22 '15 at 19:30 humcat 40829 Also I just realized this question is more than a year old.

Increase that amount for games and graphics, or if you're seeing subpar performance.

Tell us how we may improve it.

So I just installed my Parallels copy that I have and I noticed it does the exact same thing. We thought it was a good idea to start our memory performance testing at below optimum levels, to determine how performance does or doesn't improve as memory is increased.

so far. With Windows 7 installed, along with our two favorite cross-platform benchmarking tools (Geekbench and CINEBENCH), we're ready to find out which settings have the most effect on guest OS performance.

Performance After testing Parallels with memory allocations of 512 RAM, 1 GB RAM, and 2 GB RAM, along with testing with multiple CPU/Core configurations, we came to some definite conclusions.

RAM Allocation http://technologyprometheus.com/cpu-usage/bf1-high-cpu-usage.html Even so, the improvement in the Integer and Floating Point tests with multiple CPUs/Cores is probably well worth the slight drop in Stream performance for most users.

Our CINEBENCH results also

I think they are aware of the problem but do not know how to fix it. Also, I see the specs of your rMBP are similar to mine - I have my VMs set to use 2 cores for intensive tasks (databases and rendering) and 1 core However, the Geekbench Stream test, which measures memory bandwidth, showed a noticeable decline as we added CPUs/Cores to the mix. Chrome 26 is a base install with default settings and no extensions are installed other than the default 'Google Docs' extension, which is disabled.

When to shutdown virtual machine? Doubling the number of CPUs/Cores didn't produce a doubling in performance. I have also found the following thread on the Parallels forum and mentioned my problem there, too: prl_vm_app @ 99.9% CPU on Mac OS X 10.7 - Page 3 - Parallels
