In Tomcat 8.5 and higher, NIO will always outperform the BIO connector because the BIO connector has been completely removed. BIO cannot be meaningfully-used with any asynchronous use such as Comet and, more recently, Websocket. NIO will always outperform BIO in other cases when you are measuring the performance of requests-per-thread. With NIO, you can handle a much higher number of simultaneous requests with a smaller number of request-processing threads, especially when HTTP keepalive is being used (which should pretty much be "always"). In terms of throughput, the difference between NIO and BIO is negligible. In terms of CPU, NIO is a bit more stressful for the CPU than BIO, but the benefits far outweigh the difference. > What would be high level design of corresponding performance tests > showing advantages of each connector ? Jean-Frederic has some recently-presented slides comparing BIO to NIO. I'll see if I can find them and put them online. - -chris -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJXQz6DAAoJEBzwKT+lPKRYnJsP/j6Aa3+Ss86WdMfWZ1+j2O+j qoplBMOPicZDsfnucG1W8ztUprJcgjzcnxFbww8jvpjQs8xuoF/enRVY4Lq2nIbc vIU5xVB684CKL401Ram0hIdJLSkrl/y4XaeLeywOwsXVx6qvIrML8qdsHUQLp1xC g6kZqaqhAibxKT1LuK9/WtURXXYMWc70lt7bTu7y6PRLybUWnYvBMwQWGMsavKKu jVALCJeJznEos3TdM5P/1C2k/27M1Mh+CyPIbL/az2lVP/7S7Q7RydBrh205WU6r AvDJ8KA8mbhiQ57DDhK96KOXcCjDinGYOBGMdGfY8Uv0KGrtz6s6bDYx4O40UKtH bRLNxNqz7/hfl8Pzmgho+UOg2/vAIIUcbZ78+i2Hx+tQKiNIASbg73LJ34V1Ms24 iu0QHNpCQI9MaYgnjXe40a3bwPYK79wzD2i459bxkiRmneuBaaH1KQ9PsG3amVgW 56iCbyfAvfnK5Ooqp+ag038kUfqWa//ACtLXKGsGjEa5V9iKiTrDcKUNxysC5zsR uAr8tXqeNuAPKZA+ET0oCKY/gUa4iU+9rlMqW3XXrWDS7BkQKng44W0h3bEo5evt Vy5/isS8bDQ+53ZyQr3jatneTpHz4Ka+BOFkrRgNY2kkTU+PbFwLV8lUB4fZgwY8 +SqV8S0CfEfxUGrqHrNb =e1cY -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
