Hi there,

I have indexed 11 Million Documents to a standard ES-Index (   
products\_de-de) and an AppSearch index (   
.ent-search-engine-60547892750dd40d0e4018ce)

 ![image](https://us1.discourse-cdn.com/elastic/original/3X/9/e/9eaf37ccc96a976d8ba2e861e9b2c0f214f5dab6.jpeg)  
Actually the AppSearch Index is 6 times the size of the normal index, while there is an additional   
.ent-search-document-backend-60547892750dd40d0e4018ce index with roughly 9GBs of size.

This also contributes to enormous load times for a simple search with 1 facet of around 800ms, which also doesn't get cached (fired the same query 10 times without a decrease in load performance), at the same time app-search and Elasticsearch both have \> 15GBs of free memory.

The same multi\_match query with 1 agg on plain ES takes first ~150ms and then decreases to 35ms in the second request.

We are running the ES Stack on 7.11.1 - maybe this is a faulty version ?

Hi Philipp,

We already have some significant improvements built and they will be shipped in the near-term version. I'll reply to this thread when the new version is available for download.
