And the Reactor class uses cpu count IO Threads. So kinda 10.\n\nIm now using this configuration, before the default from the wiki page.\n\ndef h2Config = H2Config.custom()\n                    .setMaxConcurrentStreams(100)\n                    .setInitialWindowSize(1048576 * 2)\n            // .setPushEnabled(false)\n                    .build()\n\n            def ioReactorConfig = IOReactorConfig.custom()\n                    .setIoThreadCount(Runtime.getRuntime().availableProcessors() * 2)\n                    .setSoTimeout(Timeout.ofMilliseconds(60000))\n                    .build()\n\n            def client = H2AsyncClientBuilder.create()\n                    .setH2Config(h2Config)\n                    .setIOReactorConfig(ioReactorConfig)\n             .disableRedirectHandling()\n             .disableAutomaticRetries()\n                    .build()\n\n            options = FirebaseOptions.builder()\n                    .setCredentials(GoogleCredentials.fromStream(resource))\n                    .setHttpTransport(new ApacheHttp2Transport(client))\n                    .build()\n\nSo the latest firebase version sends at 1/10 of the original speed?
