To get the elapsed time in seconds, you can use timeit.default_timer(): import timeit start_time = timeit.default_timer() # code you want to evaluate elapsed = timeit.default_timer() – start_time timeit.default_timer() is used instead of time.time() or time.clock() because it will choose the timing function that has the higher resolution for any platform.
Never mind, figured it out. After you have typed in one value, press ENTER at the end of the textbox. This causes another textbox to be shown under the current one, into which you can type an additional value.
I found an easy solution Step1. connect to DB with an admin user using PLSQL or sqldeveloper or any other query interface Step2. run the script bellow; in the S.SQL_TEXT column, you will see the executed queries SELECT S.LAST_ACTIVE_TIME, S.MODULE, S.SQL_FULLTEXT, S.SQL_PROFILE, S.EXECUTIONS, S.LAST_LOAD_TIME, S.PARSING_USER_ID, S.SERVICE FROM SYS.V_$SQL S, SYS.ALL_USERS U WHERE S.PARSING_USER_ID=U.USER_ID AND UPPER(U.USERNAME) … Read more
The VisualVM which comes with jdk6 has a basic profiler inside it. VisualVM is provided with the jdk, so if you have the jdk6 installed, you likely have it installed as well. https://visualvm.github.io/
You can use the log_statement config setting to get the list of all the queries to a server https://www.postgresql.org/docs/current/static/runtime-config-logging.html#guc-log-statement Just set that, and the logging file path and you’ll have the list. You can also configure it to only log long running queries. You can then take those queries and run EXPLAIN on them to … Read more
A friend and I have written a Python profile viewer called SnakeViz that runs in a web browser. If you are already successfully using RunSnakeRun SnakeViz may not add that much value, but SnakeViz is much easier to install. Edit: SnakeViz supports Python 2 and 3 and works on all major systems.
First: Time sampling profilers are more robust than CPU sampling profilers. I’m not extremely familiar with Windows development tools so I can’t say which ones are which. Most profilers are CPU sampling. A CPU sampling profiler grabs a stack trace every N instructions. This technique will reveal portions of your code that are CPU bound. … Read more
gprof (read the paper) exists for historical reasons. If you think it will help you find performance problems, it was never advertised as such. Here’s what the paper says: The proļ¬le can be used to compare and assess the costs of various implementations. It does not say it can be used to identify the various … Read more
I have used JetBrains dotTrace and Redgate ANTS extensively. They are fairly similar in features and price. They both offer useful performance profiling and quite basic memory profiling. dotTrace integrates with Resharper, which is really convenient, as you can profile the performance of a unit test with one click from the IDE. However, dotTrace often … Read more
Under Trace properties > Events Selection tab > select show all columns. Now under column filters, you should see the database name. Enter the database name for the Like section and you should see traces only for that database.
