Hello,
I am currently trying to integrate Ignite 2.7 into an existing Web
Application built on top of Apache Tomcat. Therefore I use it in an embedded
mode.
While everything works fine so far, I came across an issue regarding the
idle CPU consumption. On my developing machine (Laptop, Inteil I7), Ignite
consumes about 20% of CPU according to the task manager.
Our production environments are usually virtualized, thereby I expect the
CPU usage to be higher within those scenarios.
As we use Ignite to execute complex tasks only, is there a way to decrease
the idle CPU consumption (and thereby free resources for frontend tasks)?
After some debugging, I came across the "sys-" Threadpool. The CPU
consumptions seems to origin in one thread of this pool (usually the last
one spawned). Yet I could not figure out a solution.
I use the following configuration:
IgniteConfiguration cfg = new IgniteConfiguration();
cfg.setIgniteInstanceName(instanceName);
cfg.setConsistentId(nodeName);
cfg.setActiveOnStart(true);
cfg.setAsyncCallbackPoolSize(4);
cfg.setAutoActivationEnabled(true);
cfg.setNetworkSendRetryCount(5);
cfg.setDeploymentMode(DeploymentMode.PRIVATE);
cfg.setClassLoader(Thread.currentThread().getContextClassLoader());
cfg.setPeerClassLoadingEnabled(false);
cfg.setPublicThreadPoolSize(4);
cfg.setLoadBalancingSpi(new AdaptiveLoadBalancingSpi());
TcpDiscoveryVmIpFinder ipFinder = new TcpDiscoveryVmIpFinder();
ipFinder.setAddresses(Arrays.asList("127.0.0.1:48500..48503"));
TcpDiscoverySpi discoverySpi = new TcpDiscoverySpi();
discoverySpi.setLocalPort(48500);
discoverySpi.setLocalPortRange(4);
discoverySpi.setIpFinder(ipFinder);
cfg.setDiscoverySpi(discoverySpi);
TcpCommunicationSpi communicationSpi = new TcpCommunicationSpi();
communicationSpi.setLocalPort(49100);
communicationSpi.setConnectionsPerNode(4);
communicationSpi.setMessageQueueLimit(2048);
communicationSpi.setIdleConnectionTimeout(100);
cfg.setCommunicationSpi(communicationSpi);
cfg.setMarshalLocalJobs(true);
cfg.setIncludeEventTypes();
Thank you very much in advance.
Regards
