TLSSocket.prototype.setMaxSendFragment - tls - Node documentation
method TLSSocket.prototype.setMaxSendFragment

Usage in Deno

import { TLSSocket } from "node:tls";
TLSSocket.prototype.setMaxSendFragment(size: number): boolean

The tlsSocket.setMaxSendFragment() method sets the maximum TLS fragment size. Returns true if setting the limit succeeded; false otherwise.

Smaller fragment sizes decrease the buffering latency on the client: larger fragments are buffered by the TLS layer until the entire fragment is received and its integrity is verified; large fragments can span multiple roundtrips and their processing can be delayed due to packet loss or reordering. However, smaller fragments add extra TLS framing bytes and CPU overhead, which may decrease overall server throughput.

Parameters

optional
size: number = 16384

The maximum TLS fragment size. The maximum value is 16384.

Return Type

boolean
