Profiler

[ShaDoOoW]

I make new module with location where is one NPC.
In onspawn have my testing script, I wanted try what is better for optimization scripts. But ...

I run server once and nwnx_profiler.txt write:
my_script 15731msec 1calls*

At second start without changes in module there was modification:
my_script 10528msec 1calls*

How is it possible, or on what depends time to do a script?

A lot of things are influencing performance.
cpu, disk io, swapping, (with a database: table size, indexing etc) etc

If you are testing performance on a certain script, make sure to measure the execution time several times. After a few runs (say 10-20) you can calculate the average execution time. If there are really high or low values (compared to the rest) you could eliminate them from the average.

Do the same for your new script to see if performance increases.

If you use a database like MySQL, you could tune your queries seperatly on the mysql command prompt. Try to add some index combinations on search keys and watch the execution times.

ok and when i run server all script take the same time to do. So when i run server and there will be time to do 1 script less than average that means that this run will best for start module becose all scripts take less time ?

I'm sorry but I don't understand what you mean.

Uh, how do you make a script run for 15 seconds ? I would really like to know how you got around the TMI limit for that long .

On the other hand: Your operating system is a multitasking one, and if scripts take THAT long to execute, it will suspend nwserver.exe every nn milliseconds (10-75ms, not sure, just an estimate) and run something else. That time counts towards the script execution time as well. Especially the NWN client is notorious for stealing CPU time from the server, try to give nwserver.exe a higher priority with the Windows task manager.

Note: Normally, scripts take not more than a couple of milliseconds and therefore the profiler does not take task switches into account.

I thought I would put this in this topic since it's what I wanted to speak about.

I downloaded NWNX and NWNX Profiler, with the intent purposes of running scripts to see how hoggish they were.

I plop NWNX.2, NWNX.ini, nwnx-module.dll, madCHook.dll, and nwnx-profiler.dll in the NWN directory, but it appears I'm doing something wrong or not right.

This is what I get all the time

which is pretty grainy. If you can't see what is happening I will try and clean it up.

I don't see any statistics like I had hoped.

First, did you add the script hooks into the module? That is still needed.

Second, the results are logged into a txt file in your logs.0 directory. You simply open that text file to see the results. They do NOT show in the graphical interface; way too much data is being saved too often

Thanks for the reply. I trust that this log file will change dramatically when I put in the script hooks. Which leads me to my next question. Where do I get script hooks, and do I put them in the NWN directory with the rest.

Just thought I'd mention this although if it's really obvious, sorry I said anything. According to the instructions for the NWNX2 program and the profiler itself. I couldn't find anywhere, where it said to do anything other then put the files I mentioned in the NWN directory.

No script hooking necessary for the profiler. Just run your module using nwserver with the nwnx stuff installed, and check out the logfile nwnx_profiler.txt in one of the logs.0,1,2 directories...
