[SOLVED]openbay extension - slow website

Hello everyone, today my site started to load slower than usual. The speed have never been great, but it got even worse today. So I checked the access log of the site and I found something that seems weird to me :
"POST /admin/index.php?route=extension/openbay/ajaxOrderInfo&token=553a5dc1eeta789f25e07fd206eb1baf&order_id=3&status_id=1 HTTP/1.1" 200 - "https://......./admin/index.php?route=sale/order/info&token=553a5dc1eeba789f25e07td206eb1baf&order_id=3"
because I haven't installed this Openbay extension, though I have it with the OC installation. I'm using OC 1.5.6.4 version.
I found on the net, that this Openbay extension have/had some vulnerability issue. Does anyone know of this is something normal, this POST call to openbay extension, that i haven't installed in the site even, and whether it could be the reason for the slower speed?

I have uploaded a screenshot of partial http://www.webpagetest.org speed test result, and there is big time in waiting for any response from the server, do you think this could be the processing of database queries, or it could be something else?

There are about 500 products in the site.

If anyone have some ideas, I'm not sure how to deal with this.
Thank you.

As soon as I started to publish links on this forum, I got hit by 3 spiders, one of them from amazon...
So, one of them possibly tried to check your Options and called the link. They know, what to call, OC is no secret to them.
That's why I love all this LIKE- and other Sniffer-garbage on Webpages so much, their (paid) purpose is to make your Site VISIBLE and known to/for the BIG Competitors as soon as you enter the Scene.

You see, nothing really comes for free...

good Luck
