Performance Tips needed for Nop 2.20

Hi, I'm testing Nop 2.2 without any modification for my requirement. I have db with appx. 20k products and more than 70 categories.

I have setup it on my server for testing and found that after few visits, IIS starts using almost 90% of memory. For first 15-20 minutes it works fine, but after several users (3 to 4 users) testing it, it starts to use almost all of CPU available.

I have tested it on another PC too with the same behaviour. Note that I'm using Nop Default theme just to make sure its not custom theme related issue.

I see in resource monitor that IIS is using most CPU usage, next is SQL, but that is fine. My concern is for IIS. Once I stop IIS server, it goes to 2-3% and stays there. Note that there is only one web application hosted, i.e. Nop Commerce 2.2. I had similar problem with Nop 2.1, so I waited for 2.2 and tested again. But this is still not much improved as visible from results.

I am looking forward your help to track the issue as what is causing this behaviour, is it number of products causing this? I am looking forward your help to trace it, and fix it.

Does anyone using Nop 2.2 on shared environment, with few thousand products? Please advise how to improve performance?

Thank you

Any one having same issue, or Is it only me having this issue?

Any one here using NopCommerce 2.* with product base with more than 15-20k products?

Andrew!
I do not know about the performance of jubilation nopcommerce 2.20 - fast. First download the new user and has remained slow. I left your demo example that install after the official publication of Version 2.2
Day 3 I did not change. And then shook the Russian language in the language and replace text in your topic on your own. No odnin. Cshtml no. Dll did not change. Nothing else has changed. The site began to load more. This is more than 60 seconds. Nothing else has changed. http://decareto.com
This is how you explain this? Or is it already pritenzy for hosting? Or a reaction to the Russian language?
It's all totzhe hosting http://arvixe.com
Maybe the guys from this host can respond to this miracle.
No decent person will not want to wait 60 seconds or more to view this site. Which makes sense to change the markup if the demo does not work.
And if your goods are replaced by their website that will be very difficult to load.

Anyone here with tips on performance?

In demo first loading >> 8sec. 92 products in base. Сontinue to fill the base.

I have 18k + products in my test db, and it loads fine, but uses 100% CPU constantly after 20-30 minutes of usage with appx. 3-4 users browsing / shopping on site.

Has this problem been resolved?

I am preparing to make the jump to 2.2 with 50k+ products and wandering ..

Yes, It has been resolved. The problem was caused by modification made into Category Navigation. Refer to post, https://www.nopcommerce.com/boards/t/2558/change-category-navigation-to-correct-xhtml.aspx

We have stored menu in cache and it resolved.

Although it has been solved, there is still other performance related issues like high constant cpu usage, ex. it takes appx. 20-27% cpu for one request, even after dozens of optimizations made.
