#Anysend speed driver#
Specifies the number of send packets the WAN miniport driver (or its NIC) can accept at a time, effectively how many NDIS_PACKET-type send packets the WAN miniport driver queues internally. NDISWAN defaults a ReceiveSpeed of zero to 28.8 Kbps. This speed is in units of bytes per second. Specifies the speed at which the WAN miniport driver can receive data from the network on this VC. NDISWAN defaults a TransmitSpeed of zero to 28.8 kilobits per second (Kbps). Specifies the speed at which the WAN miniport driver can transmit data over the network on this VC.

This VC status is indicated up to higher-layer drivers by a CoNDIS WAN miniport. The WAN_CO_LINKPARAMS structure describes status associated with the virtual connection (VC) on a WAN NIC. x, see Porting NDIS 5.x Drivers to NDIS 6.0. For new NDIS driver development, see Network Drivers Starting with Windows Vista. x has been deprecated and is superseded by NDIS 6. I'm curios about it as my ESP32 module running the same code is limited to 0.053MBit/s which was modem speed 20 years ago (ok, maybe off-topic as still under development, but maybe it is affected by the same wrong setting I missed?).Note NDIS 5. Why is it far slower than the server implementation above? Are there options I missed to speed it up? The speed was also not affected by changing the receive timeout between ms, and not by the NoDelay setting. This speed was quite constant for all packet sizes tested from 32 bytes up to 5840 bytes in each client.read() call. (2) The web client implementation delivers roughly 1.5MBit/s, tested here in the company where the internet connection is not the limiting factor (at home I got 0.8MBit/s, the slow DSL connection may be blamed for). my Win7 computer reaches up to 10MBit/s with IE,Firefox and Chrome while my Samsung smartphone is limited to 6.0 MBit/s, and they both can perform faster on file downloads.Īre there other tricks to go faster? Can the ESP be told to use a larger TCP/IP window size to send out even more data before they have to be acknowledged, to get independent from ACK latency? The ESP8266 seems to wait for an ACK for any send request so TCP/IP speed depends heavily on ACK delay of the client.
MTU size) packets to force the client to acknowledge them as fast as possible without waiting for more data. (1) The web server implementation delivers up to 10MBit/s as I used the trick to send 2920 bytes (2x max. Negative aspect is that the speed measurement is affected by internet infrastructure, positive aspect is that the same source code can be used for ESP32 as well (as currently no WifiServer class is implemented there). In this case the ESP consumes the data so it's just the opposite to the web server implementation. Idea behind is to create a simplistic web client on the ESP8266 which connect to an external AP downloading a file from an internet source.
#Anysend speed serial#
The file is simulated by static RAM content, the speed measurement is done on the module itself and presented on both serial console and the web page itself. Idea behind is to create a simplistic web server on the ESP8266, working with external AP or by creating an own AP, and any browser on PC or smartphone can connect to it to download a file. The attachment of this post contains sample code for simple TCP/IP performance testing.
