Application profiling / performance testing,"<p>(Note: I want to test it on android)</p>

<p>Hi,</p>

<p>I have an application in react native and a similar application made with flutter. I want to profile / test it and see cpu usage, check when they drop frames, etc.</p>

<p>I know that applications in debugmode are worse in performance. So I thought I have to test these two applications in release mode, because I dont know how much debugmode hold these applications back.
But from my understanding android profiling does not work in release mode (don't know about systrace, still have some problems with it).</p>

<p>So my question, how do I compare these 2 apps? Is there a way to do with release builds? Or should I test and compare it with a debug build?</p>

<p>[Edit]
I read that flutter has a profile build which builds closely to a release build, is running in debugmode and turning off dev mode in react-native about the same?</p>

Performance testing bottneck microsercice,"<p>I am using jmeter to load test my APi server(running on tomcat) which inturn calls a micrroservicr using thrift.(20k requests/min)</p>

<p>So, I suspected probably API is queueing up the responses because it is unable to accept the rate at which its receiving response from the microservice.To address the same I doubled <code>Xmx</code> and <code>Xms</code> value of my API java application.</p>

Front End Performance testing Automation,"<p>Currently little to no front end performance testing done on our enterprise web application (Java, Hibernate, Oracle, HTML/CSS/JavaScript &amp; In-house templating language).</p>

<p>We recently setup Jenkins and are slowly trying to automate things.</p>

<p>I know straight off the main problem points with our front end performance (No Minifying, compression, bundling, etc.....) </p>

<p>Application is built nightly via a jenkins task. (Using Maven)
I'd like to use a tool to identify current baseline metrics and going forward have tests run nightly and alert if baseline values are exceeded.</p>

<p>I had a quick look at <a href=""https://github.com/GoogleChrome/lighthouse"" rel=""nofollow noreferrer"">Lighthouse</a> and notice it provides a nodejs module for running on command line as well as it been possible to run as a grunt task via jenkins.
<a href=""https://kitconcept.com/blog/continuous-performance-analysis-with-lighthouse-and-jenkins/"" rel=""nofollow noreferrer"">This</a> article was useful on setup.</p>

<p>Has anyone experience using this approach with these tools?
Any suggested better approach?</p>

SQL query Performance testing regarding cache,"<p><strong>The situation</strong>
We are planning to migrate our entire (production)DWH to a new cluster. One of the requirements is that the new cluster is atleast as fast as the current cluster. This calls for performance testing with the current cluster serving as a baseline.</p>

<p>When conducting these tests we want both enviorments to be near identical in terms of behaviour. </p>

<p>I can already clone the user behaviour from the live production cluster and execute it on the new cluster. Leaving the cache to be tackled.</p>

<p><strong>The catch</strong>
Since we are going to compare this new cluster to the live production enviorment I can't simply clear the cache of both servers. Clearing the cache of the new cluster would be possible since it isn't in production yet. However I am not going to clear the cache of the live production cluster since this is still being used and will have a big impact on the performance.</p>

Web Performance Testing - Code behind value as dynamic parameter,"<p>I've been put in charge of developing a performance test for one aspect of the system my company develops. The idea is that you upload a document, click a button, which then does a whole bunch of steps behind the scenes. The document is given a unique ID once it's uploaded, which I need to capture as a dynamic parameter so that the test can be repeated. The application is written in ASP.NET/C#, and <em>I have no ability to view the source code or modify it in any way</em>.</p>

<p>Visual Studio does not automatically pick this up as a dynamic parameter, despite the fact that it needs to be one.</p>

<p><strong>Process Information</strong></p>

<ul>
<li>The id is generated when the document is uploaded. It's stored in the link that you click to process the document.</li>
<li>The id is grabbed from the code-behind at run time, through Razor code.</li>
<li>It is not passed through the referer to the next page, but somehow appears there anyway.</li>
</ul>

<p><strong>Things I've Tried</strong></p>

<ul>
<li>Extracting the value from the first page. This just results in having C# put in the id location instead of the actual value. Eg. 'DataItem.GetMember(""ObjectId"").Value' instead of '600-562949958140473'</li>
<li>Creating an intermediate step to get the id before moving onto the real page. I'm not sure how to do this successfully - my attempt just resulted in an additional failed step.</li>
</ul>

<p>This is my first time working with Web Performance Testing, though I have used CodedUI. So for any explanation, please assume I'm an idiot.</p>

and test cases from Test Fragment 1 runs first multiple time based on thread count and then test case from second fragment runs</p>

<p>TC2: Fetching user count using API </p>

docker swarm - Performance Bottle Neck,"<p>While doing Performance testing in Docker Swarm cluster, the Transactions Per Second(TPS) is not going beyond 400 TPS and the response time is gradually increasing.
While doing Performance testing on one server the TPS is around 200.

But the TPS is not going beyond 400. It seems the Leader is not able to handle more than 400 requests and distribute to the other 9 nodes in the cluster.</p>

<p>I wanted to pass an Arabic word as a value in the POST Data, but when I see the Request using the View result tree I can see that the Arabic word is getting replaced by ""????""</p>

<p>I have tried checking/unchecking the Encode checkbox from the Http request it doesnt works.</p>

How to run multiple .jmx recorded script at one instance on non-gui mode without Any plugin?,"<p>I am doing Performance testing for my web App with JMeter.</p>

<p>I tried running multiple (more than 1) .jmx by merging all scripts in one, but it doesn't work on Jmeter non-gui mode. So is that possible to run multiple .jmx recorded scripts from Jmeter non-gui mode without using any plugins like Maven or Ant plugins? Keep in mind that all different scripts have different credentials to login into web App and executing different tasks.</p>

<p>Thank you in advance.</p>

Why Python3.6 showing better results than 3.7?,"<p>I have the following code (Its useless, just for performance testing)</p>

<pre><code>class A:
    def __init__(self, i):
        self.i = i

start = datetime.now()
foo = {}
for i in range(10000000):
    foo[i] = A(i)

print('\nSpent: [ {} ] seconds!'.format((datetime.now()-start).total_seconds()))
</code></pre>

<p>The thing is, that when I run it with Python3.7 I get the following results</p>

<pre><code>Spent: [ 7.644764 ] seconds!
</code></pre>

<p>But when I run it with Python3.6</p>

<pre><code>Spent: [ 6.521555 ] seconds!
</code></pre>

<p>So the question is, do I misunderstand something or the older python is faster and I should use the old one?</p>

<p>UPD: As suggested in the comments, I've used <code>timeit</code> module, here the results</p>

<pre><code>python3.7 -m timeit '""-"".join(str(n) for n in range(2000000))'
1 loop, best of 5: 499 msec per loop

python3.6 -m timeit '""-"".join(str(n) for n in range(2000000))'
10 loops, best of 3: 405 msec per loop
</code></pre>

<p>The results with <code>timeit</code> are still bad for 3.7, is it really slower than 3.6 ?</p>

Nodejs number of concurrent request affect performance,"<p>I am facing a very serious performance issue in our project. In one of the specific Get request, I am doing multiple(sql queries to database). I prepared all promises and Promise.all them at the very end.</p>

<pre><code>const getA$ = getAFromDB();
const getB$ = getBFromDB();
....

const [A, B, ...] = await Promise.all([getA$, getB$]);
</code></pre>

<p>I used Jmeter to performance testing my endpoint, the below behaviour is observed.</p>

<p><code>1 request:  Average response time :  100ms</code></p>

<p><code>10 concurrent request:   Average response time : 200+ms</code></p>

<p><code>20 concurrent request:   Average response time : 300+ms</code></p>

<p><code>50 concurrent request:   Average response time : 500+ms</code></p>

<p>The number of concurrent request increases, the higher average response time I got. I configured my sequelize.js connection pool </p>

<pre><code> ""pool"": { max: 55, min: 0, idle: 10000 }
</code></pre>

<p>What is wrong here ? Am I not using node correctly or this is the general behaviour ?</p>
