My ElastiSearch query in .net is fetching data too slow.help

Question

I don't know why response needs too much time to query data.

 

var response = _client.Search<ModelName>(s => s

.Index("products")

.From(0)

.Size(10)

.Query(q => q

.MultiMatch(m => m

.Fields(fields => fields

.Field(

p => p.ManufacturerPartNumber

)

.Field(

p => p.Name,5

)

.Field(

p => p.FullDescription

)

.Field(

p => p.ShortDescription

)

.Field(

p => p.Sku

))

.Query(term)

.Type(TextQueryType.BestFields))));

var productIds = (from hits in response.Hits

select hits.Source.Id).ToArray();

var models = _productModelFactory.PrepareElasticProductOverviewModels(productIds, false, true, _mediaSettings.AutoCompleteSearchThumbPictureSize).ToList();

in kibana in took it writes 264

GET /products/_search

{

"query": { "match_all": {}},

"size":10000

}

 

pls any suggestions?
