I had same problem on server 2012 R2 and I threw opera away

reinstalling cleaning etc... nothing helps, everything after upgrade to 30

in new opera can't disable cache so command line is even less possible

Yes I know new is related to piece of shit from Google

But old Opera was doing without it (Firefox can also disable) and finally can use RAM cache ?

As in topic, can block access to cache folder by setting proper permission but is not the point, how to do it in more elegant way ?

I already know what is causing the problem, I moved cache to other slow drive using symbolic link, Opera during first start rebuilds cache or something like that, which is slowing down Opera during start

Now I have to find how to disable or block cache

Sorry for long delay, I can't find those files

First opera start, after system start is always very slow I have to wait up to one minute to see Opera window, is very irritating and confusing

How to speed up start process ?

I using laptop with with i7-7200m and GPU Nvidia GTX-880m, SSD and plenty of RAM so it's not problem with insufficient computing power or slow HDD
