Would love to hear tips to get fastest websocket connection

Hello, im trying to get the fastest weboscket connection and looking for ideas including
inserting the data into a database.

I tried using nodejs with mariadb however i'm getting gaps in the data because the script is not fast enough (there is some seconds with 5-10 rows so the script can't handle such high inserts, when im plotting the data i can see it faster but looks like the insert side makes it slower)

I would love to hear for any tips
Thanks!!
