Host send network speed slow when VM is running with bridged adapter

Description
We're using VB to run Linux guests on some of our machines. These use Bridged Adapters to allow the whole network to access them, and for years it's been working fine. With the 4.2.10 update, and also in 4.2.12, the Host's network send speed is severely reduced when the VM is running. This is tested just using normal Windows shares from the Host to any other machine on the network. Normal transfer speeds are upwards of 90MB/s, but when the VMs are running, it's around 20MB/s. Turn the VM off and the speed returns to normal. Turn it back on and speed is reduced again. Receive speed is fine, only send speed is affected.
When we downgrade to 4.2.8, the issue disappears entirely. We've got several machines that all have the same issue.
The hosts are all windows 7 x64 Ultimate. The guests are a mix of Debian 7 and Ubuntu 12.04, and all they do is run Apache or MySql. The guests are not under any load during these tests, and are generally idle.
Please reopen if still relevant with a recent VirtualBox release.
