Slow Response Time on Nop Commerce Admin Panel when multiple operators are working

We have nop commerce 2.3 for our live site, with appx. 100000+ products, 800 categories and 5000 Manufacturers.

It is a live site hosted on dedicated Server with Quad Core processor & 16 GB Ram.

While a team of 30 person is handling the site operation which includes adding new products, updating existing products and pictures, order processing, etc. Most of the time we are facing a lot of issue with the Administrator Panel of the Nop Commerce. Issues like sql time out are very common. And the admin panel speed is deadly slow, one person is able insert almost 8 products only on an average daily. Which is giving us a lot of pain.

To fix issue, we have hosted application on our local interanet server connected to live db server. But has the same issue. Just noticed that now live site is not having an issue while we work on the admin panel. But still there has been no real improvement on admin side when we work in admin panel. If just one person work on admin, then the site speed is good enough to support his operations, but for the team its just not sufficient.

What are your recommendations and suggested speed to improve this situation.

This issue is fixed in the upcoming version 2.60. See changeset c2b6bb70b969
