AMS help with articles

[Name12]

Please tell me, I parsing articles from another site and load in AMS in different categories, and if a lot of downloads (from 10k approximately), then begins to stumble site, or rather the database, the more articles - the slower authorization / registration, sometimes even error 500 after authorization, I have to disable the plugin or delete items.

Is there a way to load 100k-200k articles and that all works well?
