### Pre-check - [X] I am sure that all the content I provide is in English. ### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dubbo/issues?q=is%3Aissue) and found no similar issues. ### Apache Dubbo Component Java SDK (apache/dubbo) ### Dubbo Version Dubbo 3.2.6 linux: Linux 5.15.80 i check code in branch 3.3 ### Steps to reproduce this issue I want to deploy a dubbo reference with 2000 providers for test . It is a 15 addition time cost when i try to ‘notify’ these provider url when i use new code in 3.2.6 zookeeperRegistry used. ``` // old code URL url = URL.valueOf(providerUrl) // new code URL url = new DubboServiceAddressURL(rawProvider.getUrlAddress(), rawProvider.getUrlParam(), copyOfConsumer, overrideUrl)) ```  There are some reflection operation and do not be cached . it is ok in `export` but refer process this cost will be long when proveriders and methods list grow ``` // org.apache.dubbo.common.utils.SerializeSecurityConfigurator#registerInterface if (!autoTrustSerializeClass) { return; } Set<Type> markedClass = new HashSet<>(); checkClass(markedClass, clazz); addToAllow(clazz.getName()); Method[] methodsToExport = clazz.getMethods(); for (Method method : methodsToExport) { Class<?>[] parameterTypes = method.getParameterTypes(); for (Class<?> parameterType : parameterTypes) { checkClass(markedClass, parameterType); } ``` i want to know is it necessary to be fixed？ and if i work on it should it is will to use existed service cache in dubbo like ‘watch org.apache.dubbo.rpc.model.ReflectionServiceDescriptor ' or some dependency like org.springframework.util.ReflectionUtils. ### What you expected to happen there are 2000 instance in registry。 when i change timeout config in config center。 client do refrer all client to repalace this url。 expected to happen ： urls update in 10s when netty client do not changed actual : it takes more than 20 milites to update url in my machine it take 5ms * 2000 times to process SerializeSecurityConfigurator addition ### Anything else _No response_ ### Are you willing to submit a pull request to fix on your own? - [X] Yes I am willing to submit a pull request on my own! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
