Size query performance problems

[Rotem_Shriki]

Hi all,
I have 3 nodes clusters on aws (c4 instances) and 245 docs in my elastic,
when i try to limit the results to 50 using size:50, my performance degraded from 300ms to 2800ms ( without even using search_after or from) , we tried to add from:0 but without success, my logs are empty.

any help will be appreciated ,

response from server , sometimes took value is 2
"took": 1,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},

Thanks.
