Narya是基於NIO的網遊服務器底層通訊引擎，並在其上做了對象的序列化，可以直接做方法的遠程調用。今天有時間測試了下其性能。
測試環境如下
服務器
CPU：Intel Xeon X3220 2.40GHz 四核
內存：8G
操作系統：Red Hat Enterprise Linux Server release 5.4， 內核版本爲2.6.18-164.el5PAE
客戶機
CPU：Intel Xeon E5410 2.33GHZ 八核
內存：4G
操作系統：WIndow Server 2008 R2 Enterprise
關鍵測試代碼
public class TestApp {
public static void main (String[] args)
{
for (int i = 0; i < 3000; i++) {
TestClient tclient = new TestClient();
UsernamePasswordCreds creds =
new UsernamePasswordCreds(new Name("test" + i), "test");
BasicRunQueue rqueue = new BasicRunQueue();
Client client = new Client(creds, rqueue);
tclient.setClient(client);
client.addClientObserver(tclient);
client.setServer("202.75.220.231", new int[]{45312});
client.logon();
// start up our event processing loop
rqueue.start();
try {
Thread.sleep(RandomUtil.getInRange(0, 100));
} catch (Exception e) {
}
}
}
}這裏一共開啓3000個線程，模擬3000用戶，每個線程之間間隔0~0.1秒
for (int i = 0; i < 500; i++) {
service.test(client, "one", 2, three, new TestService.TestFuncListener() {
public void testSucceeded (String one, int two) {
//log.info("Got test response [one=" + one + ", two=" + two + "].");
jobCount++;
if (jobCount == 500) {
client.logoff(false);
}
}
public void requestFailed (String reason) {
//log.info("Urk! Request failed [reason=" + reason + "].");
}
});
try {
Thread.sleep(RandomUtil.getInRange(50, 100));
} catch (Exception e) {
}
}每個線程發送500次請求，每次請求間隔0.05 ~ 0.1秒，共3000x500 = 150萬次請求，外加3000次登錄與登出。
測試結果：
整個測試共持續了5分鐘左右，使用了linux的sar命令，以每5秒爲採樣頻率記錄了測試時的系統狀態

總結：
測試服務器進程CPU消耗平均爲14%，峯值在25%左右。
系統進程CPU消耗平均爲2.5%，峯值在5%左右。
網絡IO讀取平均爲592k/s，發送平均爲454k/s左右。
網絡IO讀取高峯在1.1m/s，發送高峯在900k/s左右。
使用top命令觀察內存（Resident Memory）消耗維持在110M~160M之間
5分鐘內接受請求在150萬次+，平均每秒爲5000+次。
在整個測試過程中沒有發現IO異常的情況，從測試結果來看，應該還沒有到極限，承載量還有繼續提升的空間。
