@Wilberforce, I started this conversation after seeing that on arduino my boards were doing ~100kb/sec, while on espruino it was only 1kb/sec, for server a file. In fact, I am using espruino since the v1.91, and all that time I thought it was a hardware limitation of esp8266. But it seems to me that the problem comes from the dSnd buffer sent slowly, every 200m, in small pieces of 256bytes.
As it works faster on arduino, the board is not defective. It works the same way on the 2 nodemcu-e12 v2 & v3 that I have. I restarted the router, and tried AP alone (at 20cm from my laptop), station alone and AP+ST, still the same damn result !
@MaBe, I found it at ps-poll even though it was in AP+ST mode. No change when I set it to "none" using with Wifi.setConfig({powersave:"none"}).
@ClearMemory041063, I tried without improvement also flashing the last expressif firmware with the expressif flashing tool like you did, just in case. I used "esp_init_data_default_v05.bin", because there was no "esp_init_data_default.bin". I could not get it working without also changing addresses of this file and of "blank.bin" to 0x3fc000 and 0x37e000. I got a nice :
AT+GMR AT version:1.4.0.0(May 5 2017 16:10:59) SDK version:2.1.0(116b762) compile time:May 5 2017 16:37:48 OKThen I reflashed espruino, this time with expressif flashing tool. I used the files from this url. I used the addresses from your link and I tried with "blank .bin" at 0x3FE000 like I used to do, both works same way. Still as slow as before.
I tried other browsers too, older espruino versions (v1.91, v1.94). The strangest that no one else ever have or noticed this problem before.

So you're a lucky guy, it's working fast for you for 2 different esp8266 based boards..
I really don't understand what's wrong with my nodemcu-e12. I don't have any other esp8266 to try. I installed mine with the same files, but using esptool. If I install last espressif firmware before, it wont make a difference, it will be erased by esptool, right ?
I still get a slow download.

Hmm, that's interesting, it seems hardware related. Your Sparkfun Thing dev-board rocks with espruino !
I don't get your result, with both my poor nodemcus-e12 v3 with 1.95.0 not 4mb , and my v4 lolin with 1.95.20 4mb.
Where can I find this flash map 256/256 you used ?

The other lines comes from the interval every 100ms looking and printing how long is the dSnd buffer, and I see it decreasing in my output. Strange that the interval does not seem to start at all in your setup.

Thanks @ClearMemory041063 for giving attention to my problem, and for the codes to try. You are not testing them on an esp8266, are you ? The last code makes 11,5kb minified, it does not fit, it interrupt the transfer from the IDE. So I had to remove the connecting code and reduce the data to send to 3kb. I cannot send more at once without getting memory errors.
Unfortunately, at the end, the result with ws is as slow as with http: 2.5sec for 3kb (see the code below). Maybe because ws server is built on top of an http server.
var n = 5, chk=3*1024; var tdata=new Uint8Array(chk); var i; for(i=0;i<1024;i++){ tdata[i]=0x30; tdata[i+1024]=0x31; // tdata[i+1024*2]=0x32; // tdata[i+1024*3]=0x33; // tdata[i+1024*4]=0x34; }//next i var page = '<html><body><script>var ws;setTimeout(function(){'; page += 'ws = new WebSocket("ws://" + location.host + "/my_websocket", "protocolOne");'; page += 'var t=(new Date()).getTime();ws.onmessage = function (event) { console.log("t:",(new Date()).getTime()-t,"MSG:",event.data); };'; page += 'setTimeout(function() { ws.send("Hello to Espruino!"); }, 1000);'; page += '},1000);</script></body></html>'; function onPageRequest(req, res) { res.writeHead(200, {'Content-Type': 'text/html'}); res.end(page); } var server = require('ws').createServer(onPageRequest); server.listen(80); server.on("websocket", function(ws) { ws.on('message',function(msg) { print("[WS] "+JSON.stringify(msg)); }); var t=getTime(); ws.send(E.toString(tdata)); print("n=",n,"t:",(getTime()-t).toFixed(3),"sec"); var inter=setInterval(function(){ var l=ws.socket.dSnd.length; print("t",getTime()-t,"l",l); if(l===0) clearInterval(inter); },100); // ws.send("Hello from Espruino!"); });_____ _ | __|___ ___ ___ _ _|_|___ ___ | __|_ -| . | _| | | | | . | |_____|___| _|_| |___|_|_|_|___| |_| http://espruino.com 1v95.155 Copyright 2017 G.Williams Espruino is Open Source.

I hope we can raise this upload speed limit I am reaching.
@Gordon, it looks like the chunk size you mention 256 bytes every 200ms, that's where my ~1kb per second comes from.
@ClearMemory041063, I tried your code, but it runs after 2 steps in a "Execution Interrupted New interpreter error: LOW_MEMORY,MEMORY".
There is another strange thing, drain get called one more times after res.end() has been called.
Here's the code that looks into the dSnd, 12.5sec for 15ko :var n = 5, chk=3*1024; var tdata=new Uint8Array(chk); var i; for(i=0;i<1024;i++){ tdata[i]=0x30; tdata[i+1024]=0x31; tdata[i+1024*2]=0x32; // tdata[i+1024*3]=0x33; // tdata[i+1024*4]=0x34; }//next i function onPageRequest(req, res) { res.writeHead(200, {'Content-Type': 'text/plain'}); var t=getTime(); res.on('drain',function() { print("n=", n,"t:",(getTime()-t).toFixed(3),"sec"); if (n===0){ res.end(); clearInterval(inter); print("end n=",n,"t:",(getTime()-t).toFixed(3),"sec"); } else { res.write(E.toString(tdata)); n--; } //end else });//end opr inter=setInterval(function () { console.log("--t:",(getTime()-t).toFixed(3),"res",res.dSnd.length); }, 100); }//end function require('http').createServer(onPageRequest).listen(80);_____ _ | __|___ ___ ___ _ _|_|___ ___ | __|_ -| . | _| | | | | . | |_____|___| _|_| |___|_|_|_|___| |_| http://espruino.com 1v95.23 Copyright 2017 G.Williams Espruino is Open Source.

@ClearMemory041063, I am surprised it goes a bit faster on your setup. I still got 17 sec for the 20kb, when I tried the two programs you posted. I tried with/out AP/station, no change. What version of espruino are you running ?
The only change I did was 5*4kb chunk, instead of 4*5kb chunks, as the latter stopped after n=3 (I guess a memory shortage).var n = 5, chk=4*1024; var tdata=new Uint8Array(chk); var i; for(i=0;i<1024;i++){ tdata[i]=0x30; tdata[i+1024]=0x31; tdata[i+1024*2]=0x32; tdata[i+1024*3]=0x33; // tdata[i+1024*4]=0x34; }//next i function onPageRequest(req, res) { res.writeHead(200, {'Content-Type': 'text/plain'}); var t=getTime(); n=5; res.on('drain',function() { print("n=",n,"t:",(getTime()-t).toFixed(3),"sec"); if (n===0){ res.end(); print("n=",n,"t:",(getTime()-t).toFixed(3),"sec"); }else { res.write(E.toString(tdata)); n--; }//end else });//end opr }//end function require('http').createServer(onPageRequest).listen(80);_____ _ | __|___ ___ ___ _ _|_|___ ___ | __|_ -| . | _| | | | | . | |_____|___| _|_| |___|_|_|_|___| |_| http://espruino.com 1v95.23 Copyright 2017 G.Williams Espruino is Open Source.

Thanks, very handy the .bat files. I followed the procedure with no change in speed. I placed the files in the "espruino_1v95_esp8266" directory. I ran info, erase and flash batch files.
I replugged and reflashed the WSdesp8266C. It does not go faster than before.
