Looks good in my eye, but you might wait for a second opinion for safty, as I have no intention to test on my machine. I still think it's a bad idea to mess the OS memory allocations system, but that's just my opinion.

thank You very much, @Storm
Btw I found this on the web
swap - How do I configure swappiness? - Ask Ubuntu
A swappiness setting of zero means that the disk will be avoided unless absolutely necessary (you run out of memory), while a swappiness setting of 100 means that programs will be swapped to disk almost instantly. -In topic
That's good found. I suggest you try that first, as it's easier to reverse if it goes wrong.

So my current swappiness is 60 and it's using 500Mb while rider is active,
I should make to 100 directly or something else
100 is to extreme try 80 first.

in terminal it shows 80
and
when i open it in text it shows 15
sudo nano /proc/sys/vm/swappiness
remember to reboot.
Does it work as expected?
No now using 77%Ram and 268mb swap
Also software runs with too much lag
Sad to hear that. Seems JB's rider is a resource hog, or memory leak perhaps?
Now What To DO????
I'm not sure, buy more RAM 
Perhaps another member would like to share their input on this matter.

4GB of RAM is really not enough anymore for any serious work. As you've witnessed first hand, some APPS just use more RAM then you would expect. Take GIMP for example, if I only had 4GB of RAM, I can kiss editing 5K RAW photo's goodbye. And I wouldn't be able to even edit 1080P video let alone 1400P or 4K.
So, I have to agree with Storm, its time to upgrade your RAM. Without knowing more about your computer, I have no way of knowing weather your computer uses desktop RAM, or notebook RAM, it depends on what kind of machine you have.
If you post the model of your computer, I may be able to help you find more RAM for your machine.

Hp ProBook 450G
According to Memory Stock, your HP 450 Probook has two RAM slots, and it can accept a maximum of 16GB of RAM.
ProBook 450 G4 Memory Upgrade - HP 450 G4 ProBook Laptop Memory.
This is excellent for you, because it means the RAM isn't soldered to the mobo. Since your notebook comes with 2-slots, it means you can run RAM in dual channel, to achieve the highest level of performance.
That is a listing for a 2x8GB kit. Amazon has an excellent return policy, if it doesn't work, you can return it. But these RAM chips are getting more rare as time goes on. I was trying to search for other brands that are more well known like Corsair, but they only had a single 16GB stick with a heat spreader that might be too big to fit a thin and lite notebook.
You don't want to run in single channel mode, as its slower. And like I said, a heat spreader is nice for dissipating heat and all. But they typically won't fit in thin and lites. So, I chose RAM sticks without heat spreaders. Hopefully this helps...
Video to show you how to RAM upgrade your notebook model!

Thank you Storm!
Truth is, hardware is more my specialty then software. And I find hardware solutions to be easier then software related issues. Its no secret that I struggle greatly with software related issues.
But hardware I can solve, and I always like helping other's with hardware related stuff. If I can help someone out there with that, it brings me satisfaction that I did something good. I just hope that it helps the OP.
