  • Version:
    8.9.3
  • Platform:
    win7
  • Subsystem:

for(var i = 0;;i++) {
console.log(i);
}

run this program,and the system memory that node.exe used will rise infinitely.it means that console.log has the problem of memory leaks.
thanks.

console.log() is asynchronous. See the many similar reports, e.g., #1741.

stream: improve performance for sync write finishes
42cfb80 
Improve performance and reduce memory usage when a writable stream
is written to with the same callback (which is the most common case)
and when the write operation finishes synchronously (which is also
often the case).

                                                         confidence improvement accuracy (*)    (**)   (***)
    streams/writable-manywrites.js sync='no' n=2000000                  0.99 %       ±3.20%  ±4.28%  ±5.61%
    streams/writable-manywrites.js sync='yes' n=2000000        ***    710.69 %      ±19.65% ±26.47% ±35.09%
