Max size for data transfer ?

[TkNeo]

We are using this module and its been fantastic except one issue. I have this request where i am asking the server to send 250 rows from this table. Each row has 6 columns and the connection breaks. I understand that i should not be requesting large chunks of data but just wanted to ask others if they run into similar problems and if there is a max-websocket-limit or max-best-practice-limit.

Thanks so much in advance!!
