profiling

问题 How to log, trace or get queries that an application send to Microsoft SQL Server 2008 thru ODBC driver (without modifying application...) Maybe it can be done with SQL Server itself or ODBC has some query logging? 回答1: @davispuh, you can use the SQL Profiler to trace SQL statements. you can also use the ODBC Tracing. 回答2: To Create a Trace using SQL-Profiler: On the File menu of SQL-Profiler, click New Trace, and connect to an instance of SQL Server. The Trace Properties dialog box appears.

问题 Are there any Java profiling tools that integrate with CI servers like Jenkins? I've no idea if such things exist, but what would be splendid would be some kind of test framework that yielded results like YourKit Profiler's snapshots. These would be invoked by the CI server, and the results stored along with the build. The result being that one could see a history of performance changes in code units, to aid more holistic performance investigations at a system integration level. 回答1: Take a

问题 I'm using these commands to compile the code below in order to collect edge/blocks profiling in trunk-llvm: clang -emit-llvm -c sort.c -o sort.bc opt -insert-edge-profiling sort.bc -o sort_prof.bc clang sort_prof.bc -lprofile_rt -L/llvms/lib -o sort_prof then I run the program and display the profiling information using llvm-prof sort_prof.bc, and the result is: ===-------------------------------------------------------------------------=== Function execution frequencies: ## Frequency 1. 4.3e

问题 It seems like there should be better tools out there for profiling sql than SQL Server Profiler. It takes forever to set up a profile session. I'm looking for a tool which is more like VS profiler. Just choose a stored procedure, and run it with a set of parameters, and what I should get is a profiling graph showing how long each query, SP call and function call takes, and allow me to drill down to individual statements with the parameters which were passed in. I've seen some for Oracle, but

问题 I have a simple code for a multi-threaded echo server in Java (it returns whatever received back to the clients). I'm profiling various resources of the server including the thread statistics. Below are some of these statistics as per number of connected clients. My questions is for the baseline (# of clients 0) compared with non-baselines! 1) why when a single client connects, the total thread count increases by 2? (for the rest, it makes sense to increment by 1) 2) What are the two non

问题 I have just rewritten a Matlab program in c++ as a mex-function to speed things up, with fantastic results. This optimization decision was a very very good idea, with up to a factor 20 speed up without threading. It still left me curious about what the mex-function was spending time on and wanting to identify possible bottlenecks. I'm looking for a way to profile mex-functions. The matlab profiler is not much use, and the other profilers I've downloaded (both free and trial) all want an

问题 How do you trace/profile your .NET applications? The MSDN online help mentions Visual Studio Team (which I do not possess) and there is the Windows Performance Toolkit. But, are there other solutions you can recommend? Preferably (of course) a solution that works without changing the code (manually) and that can be integrated in Visual Studio. 回答1: See also this question. JetBrains dotTrace is the best .NET profiler I have found (and I have tried pretty much every one there is), because it is
