Problem with two strange URLs slowing down shop

[Mister Denial]

Hello,

 

I have two URL's I can't really attribute and both are slowing down my shop considerably. Does someone know what these are for? (see picture)

 

Both are loading much later than the rest of the shop, and there is a 1000ms gap before that rand parameter starts loading, followed by ajax=true

 

The later, I imagine that it must be linked to the cart itself, but I have no idea what rand is good for.

 

And is there any way to speed these up?

 

I am already on a good VPS and using Page Cache module, but losing 1-1.5 seconds load time to these two urls bugs me incredibly.

 

Thanks for your time and help!

 

Dan

Ooops, corrected it now.

Hmm are those urls there when you disable your page caching module?

Brilliant idea. I was so fixated on thinking it was linked to ajax cart that the thought did not cross me that it could be linked to the Pace Cache module. It is.

 

Right now, PS 1.6.1.14 is faster without the Page Cache module than with. The TTFB is better with the module enabled, but overall page load is quicker without.
