问题 I've been getting some java.lang.OutOfMemoryError: GC overhead limit exceeded errors while running my Java app overnight: java.lang.OutOfMemoryError: Java heap space Dumping heap to java_pid6376.hprof ...

问题 I wrote a small class that executes Main() , which in turn executes A() . I expected the Main() method to be on its own at the root of the stack call, because it's the topmost function in my application. Everything that's done, should be executed by Main() . I wrote the following code to test that: namespace ProfilerTest { class Program { static int _a; static void Main() { while (true) { A(); } } static void A() { _a += 1; } } } The output of the Profiler Call Tree, however, shows that A()

问题 I tried installing TPTP profiler in eclipse indigo. However It is not working I am getting the following error. Your platform is not supported by Eclipse TPTP. The Integrated Agent Controller will be disabled. To profile on a supported host, please install and use a stand-alone Agent Controller on that host. I dont know how to check my sql memory leaks in my application. Is there any other Eclipse tool to check for memory leak. I want to profile my webapplication hosted in Tomcat. Thanks in

问题 Chrome developer tools has an option to Start/Stop Recording profiling data with respect to Memory,Paint,Screenshots,JS Profile on the Timeline tab. Once I refresh a page the recording begins automatically and stops when the page has loaded. Is there a way to 1)Start this recording in the background automatically without needing to open developer tools in chrome/node-webkit window . Maybe the recording can be enabled via some Chrome API which can be called when the application loads 2)Dump

问题 I'm trying to use SQL Server Profiler (2005) to track down some application performance problems. One of the calls being made is to a table-valued user-defined function. This function wraps a select that joins several tables together. In SQL Server Profiler, the call to the UDF is logged. However, the select that underlies the UDF isn't being logged at all. Because of this, I'm not getting useful data on which tables & indexes are being hit. I'd like to feed this info into the Database Tuning

问题 I am getting very high counts of Entity Writes in my firestore database. Write permission in most of the paths are restricted, done from back-end server using admin SDK. Only a very few paths have write access- specifically only to the users who are (authenticated & registered & joined and approved in a specific group), so even though the ways to abuse are apparently thin, yet hard to specifically identify. Only way I see- is to execute Cloud Functions on every write, and have the function

问题 I am trying to write a decorator function which converts a pure recursive function with two arguments that uses a "divide and conquer" strategy to an equivalent but more efficient one using dynamic programming. Note: it is designated to decorate two input functions. So I am trying to memoize the values but I am not sure how to correctly implement it in the form of a decorator? Also how can it decorate two input functions? EDIT: This is what I have managed to do: profile_results = {} t = {} ''
