Opera slows down when receiving email

I tried this with a simple short text email to myself. When Opera received it, the browser slowed down for a few seconds - very sticky indeed. This always happens when I receive email or news messages, no matter what size they are. It's done it on every version of Opera I've had. What on earth is Opera doing?

The notification pop-up in the systray uses a lot of cpu. So does the mail network code. If you have a message list open when you receive mail, depending on the sorting, the updating of the list might be cpu-intensive too. But, the faster the computer, the harder it is to notice. But, you can still notice it a little bit on a fast computer.

But, if you're using 12.00.1116, Opera will use your GPU to accelerate everything if your GPU is supported and you don't have have hardware acceleration disabled in opera:config. That should make Opera faster. But, it currently only supports OpenGL right now (no directx) and it's not very optimized. So, it might be worse or better with hardware acceleration turned on.

All I can say is that Opera is busy enough when it checks mail to disrupt the rest of the browser. It might be caused by disk access with the mail folder too. Don't know.

The movement of the popup didn't seem to do it. It became smoother while the popup was still rising. The delay is at the beginning, presumably when it's updating the database.

I have an i7 CPU - 8 "cores" (4 hyperthreaded) running at 5GHz (it's watercooled), plus a decent radeon graphics card. However the GPU is in use for BOINC distributed computing processing.

It's not disk access, I have 24GB of RAM so the cache is rather well used. The disk light does not operate while receiving email.

What on earth is it doing when you say it's "rather busy"? It even does it for a very small text only email. A KB of data.

Don't know for sure. Maybe some mail operations interfere with the UI message loop. Not sure.
