you listed a few issues related to network download of data.<br>
<br>
Is it possible that TB uses unbuffered I/O for these network I/O?<br></blockquote><div><br></div><div>Possibly, but I cannot really answer your questions as I am not familiar with
unbuffered I/O feature in TB or devtools and not sure it is the right place to do so :)</div><div>I am only an end-user :-)<br></div><div><br></div><div>I suspect that particular issue I reported in comment 33 may have been linked to a bug in the devtools and especially the library (<a href="https://bug1515123.bmoattachments.org/attachment.cgi?id=9032369">https://bug1515123.bmoattachments.org/attachment.cgi?id=9032369</a>) used to parse the network response and show it in the devtools network response view/editor... if you would wait long enough when TB and devtools are "Not Responding", the response data would show up eventually after a long while in black and white... before another "Not Responding" processing occurs again... till the same network response data appears but coloured formatted this time... and TB resume to be responsive again (or not, requiring a manual force close and restart).</div><div><br></div><div>In 67.x beta, the situation may have improved since then, so

may definitely have been linked to a devtools bug...<br></div><div><br></div><div>Regards,<br></div></div></div></div>
