NetworkStream.Write sometimes slow in linux #1351

Closed nullscode closed 2 years ago

nullscode commented 2 years ago

I use this code to test NetworkStream.Write speed:

var t1 = DateTime.Now.Ticks;//start

if (TcpStream != null) if (TcpStream.CanWrite) TcpStream.Write(buf, 0, buf.Length);//NetworkStream.Write

var t2 = DateTime.Now.Ticks - t1;//end

$"TCP Write:{t2 / 10}us {buf.Length} {Convert.ToHexString(buf)}".LogForDebug();//Write to logfile

then I got these logs sometimes return pretty slow this situation only in linux: 02:06:56.271|c__DisplayClass11_0|Debug > TCP Write:12us 13 AB00608D7B9100757ADA08DABA 02:06:56.277|c__DisplayClass11_0|Debug > TCP Write:5772us 13 AB0060AA839200757ADA0806BA 02:06:56.277|c__DisplayClass11_0|Debug > TCP Write:10us 13 AB00600AD89200757ADA08FDBA 02:06:56.298|c__DisplayClass11_0|Debug > TCP Write:20310us 13 AB0060E5259300757ADA08EEBA 02:06:56.298|c__DisplayClass11_0|Debug > TCP Write:12us 13 AB00603E799300757ADA0869BA 02:06:56.303|c__DisplayClass11_0|Debug > TCP Write:5518us 13 AB006099C69300757ADA0871BA 02:06:56.304|c__DisplayClass11_0|Debug > TCP Write:10us 13 AB0060FDE79400757ADA0833BA 02:06:56.323|c__DisplayClass11_0|Debug > TCP Write:19367us 13 AB00609D829600757ADA0834BA 02:06:56.324|c__DisplayClass11_0|Debug > TCP Write:13us 13 AB0060C3F99600757ADA0811BA 02:06:56.331|c__DisplayClass11_0|Debug > TCP Write:6900us 13 AB006063479700757ADA080EBA 02:06:56.331|c__DisplayClass11_0|Debug > TCP Write:10us 13 AB006033959700757ADA088CBA 02:06:56.351|c__DisplayClass11_0|Debug > TCP Write:19534us 13 AB00600BE49700757ADA08C5BA 02:06:56.351|c__DisplayClass11_0|Debug > TCP Write:11us 13 AB0060AE309800757ADA08BBBA 02:06:56.357|c__DisplayClass11_0|Debug > TCP Write:5604us 13 AB0060587D9800757ADA0800BA 02:06:56.357|c__DisplayClass11_0|Debug > TCP Write:12us 13 AB00601BCD9800757ADA08F3BA 02:06:56.376|c__DisplayClass11_0|Debug > TCP Write:19273us 13 AB0060A4199900757ADA0899BA 02:06:56.377|c__DisplayClass11_0|Debug > TCP Write:11us 13 AB0060D66A9900757ADA0898BA 02:06:56.382|c__DisplayClass11_0|Debug > TCP Write:3146us 14 AB00600155029900757ADA089FBA 02:06:56.383|c__DisplayClass11_0|Debug > TCP Write:12us 13 AB0060F9789A00757ADA08A6BA 02:06:56.402|c__DisplayClass11_0|Debug > TCP Write:19495us 13 AB006012C79A00757ADA08F2BA 02:06:56.402|c__DisplayClass11_0|Debug > TCP Write:11us 13 AB006042179B00757ADA0873BA 02:06:56.408|c__DisplayClass11_0|Debug > TCP Write:5492us 13 AB00605E639B00757ADA081BBA 02:06:56.408|c__DisplayClass11_0|Debug > TCP Write:10us 13 AB00605EB49B00757ADA08CCBA
