ssegateway is way at the top and it's used by the BlueOcean events API
This is not only affecting the UI as it seems but also the tasks that go
through the API so we have issues such as OVIRT-2608 for example.

> Hi,
> jenkins is terribly slow and becoming worse every day.
> I tried to gain some speed by adding 4 cores to the VM through engine-phx.
> It's a bit better but the real issue doesn't seem related to CPU power.
> Can anybody investigate?
