    Running Parallels 10 on Win 8.1 Pro with OS X 10.10.5 i7 16GB/512 SSD. Win 8.1 VM is set with 2 CPU's and 4GB RAM.

    Whenever I re-open Chrome with about 30 tabs to reload, OS X and Parallels slows down with high CPU usage until all tabs are full reloaded. This also happens when I have about 3 RDP sessions opened. Also happens during a large file download from the net inside Windows (i.e., 1GB ISO). So, high CPU when there are lots of network activity inside the Windows VM. Anything to tweak? Would Parallels 11 fix this?
