We want to use undertow in the following scenario (numbers are from our current app running jetty as a front end): - 24 core machine with ~60GB ram - 10000 requests per second with an average execution time of 2-4 ms - around 6000 concurrent http connections (keep-alive) - incoming request size between 2000 and 4000 bytes - response size around 4000 bytes At the moment we just copied the configuration from the Undertow class (using a HttpOpenListener). OptionMap socketOptions = OptionMap.builder() .set(Options.WORKER_IO_THREADS, IO_THREADS) .set(Options.TCP_NODELAY, true) .set(Options.REUSE_ADDRESSES, true) .set(Options.BALANCING_TOKENS, 1) .set(Options.BALANCING_CONNECTIONS, 2) .set(Options.BACKLOG, 1000) .getMap(); OptionMap undertowOptions = OptionMap.builder().set(UndertowOptions.BUFFER_PIPELINED_DATA, true).getMap(); ByteBufferPool buffers = new DefaultByteBufferPool(true, 1024 * 16, -1, 4); HttpOpenListener openListener = new HttpOpenListener(buffers, undertowOptions); worker = xnio.createWorker(OptionMap.builder() .set(Options.WORKER_IO_THREADS, IO_THREADS) .set(Options.CONNECTION_HIGH_WATER, 1000000) .set(Options.CONNECTION_LOW_WATER, 1000000) .set(Options.WORKER_TASK_CORE_THREADS, IO_THREADS * 8) .set(Options.WORKER_TASK_MAX_THREADS, IO_THREADS * 8) .set(Options.TCP_NODELAY, true) .set(Options.CORK, true) .getMap()); Some of the options i don’t understand fully (BALANCING_TOKENS, BALANCING_CONNECTIONS) some may not be applicable to our scenario. I dug around in the code a bit to find out what these settings do but i don’t feel very confident. A little help would be appreciated!
