kandi X-RAY | loadtest Summary
This package is to make load testing of APIs, such as those created with the R package plumber, easy to do. It uses Apache JMeter on the backend--a modern platform for load testing. The loadtest package is open source and maintained by the AI @ T-Mobile team. Load testing, the process of ensuring that a website or API works by simulating a massive load of traffic and seeing how the website or API performs, is a critical step in the development of production systems. R is becoming more popular for production system environments through tools such as plumber, Rocker, and the T-Mobile R TensorFlow API platform, so having a way to do load testing while staying within the R environment is useful.

QUESTION
I was wondering if using Locust as a library is more efficent than the original way as you don't have to make system calls for a new process this way thus reducing the initial delay at startup. I need to run thousands of separate loadtests for my app so it does make a difference.
...ANSWER
Answered 2022-Mar-31 at 19:20Yes it is more efficient. Starting Python, parsing all the imported dependencies etc takes some time.
How much faster is anyones guess though, and running thousands of individual load tests is not something I’ve seen anyone do, so I think you’ll have to test it yourself.
But if you are adding/removing replicas between tests, wont that be slower than restarting Locust anyway?
You can also run Locust in GUI mode and trigger a test by just sending an HTTP request to the /swarm endpoint, that should not have any significantly bigger start up time than library use.

I want to run a curl request as a pre-request script for my K6 load tests. Here is my YML file:
...ANSWER
Answered 2022-Mar-09 at 09:42The k6 Docker image runs as an unprivileged user, which is why you're not able to install curl and jq.
I would suggest you to build your own custom image using loadimpact/k6 as base, or to build an image from another base that copies the k6 binary with COPY --from=loadimpact/k6:latest /usr/bin/k6 /usr/bin/k6, install anything you need in it and run that image in CI instead.

When I run on Gitlab CI, here is what I am seeing:
Why is this error occurring when Gitlab runs it but not when I run locally?
Here is my .gitlab-ci.yml file.
Note that this had been working before.
I recently made win_perf_counters a Git submodule instead of being an actual subdirectory. (Again, it works locally.)
ANSWER
Answered 2022-Feb-03 at 12:05Probably the python libraries you are using in your local environment are not the same you are using in gitlab. Run a pip list or pip freeze in your local machine and see which versions do you have there. Then pip install those in your gitlab script. A good practice is to have a requirements.txt or a setup.py file with specific versions rather than pulling the latest versions every time.
QUESTION
Trying to run a Python program using GitLab's CI pipeline.
I had this running in Teamcity, but I wanted to try in GitLab.
First attemptI supplied an explicit list of pip install commands including wmi.
ANSWER
Answered 2021-Dec-16 at 18:17While the python:3.8.0 image has a windows architecture available, it looks like it's pulling the linux version from that tag. You can test this by adding the command uname -srm to the first line of your test scripts.
I wasn't able to get a windows docker image for python running on a shared runner, but I was able to install python 3.8 on a runner with the following minimal .gitlab-ci.yml:
QUESTION
I am trying to loadtest a simple request/reply scenario over a rabbitmq broker.
...ANSWER
Answered 2021-Dec-16 at 13:26The core issue is that you don't define in your echo service any way for Gatling to correlate outbound messages (requests) and inbound messages (responses).
Instead, you're replying with new RMQTextMessage(), so with completely different JMSMessageID and no JMSCorrelationID.
See https://gatling.io/docs/gatling/reference/current/jms/#other-options.
In your case, you should probably use matchByCorrelationId and propagate it accordingly:
QUESTION
I am trying to implement JUnit TestSuites with my 3 Test Classes and run them at the same time. But when ever I run that test suite it gives me error as Initialization Error with "No runnable method found."
This is my test Suite class named as AllTests.java
...ANSWER
Answered 2021-Dec-12 at 08:22This kind of error message usually means you are mixing up JUnit 4 and JUnit 5.
In fact, if you look closer at your stacktrace you will find that you are using a JUnit 4 runner to run JUnit 5 tests.
QUESTION
I need a powermock for private method test.
It is working well if I use only @RunWith(PowerMockRunner.class) without @PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class).
I need to use @PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class) for @autowired.
But It doesn't fail to start.

Answered 2021-Dec-12 at 02:49I solved that though adding code under line. But I can't understand what was cause.
QUESTION
I have deployed OpenStack and configured OVS-DPDK on compute nodes for high-performance networking. My workload is a general-purpose workload like running haproxy, mysql, apache, and XMPP etc.
When I did load-testing, I found performance is average and after 200kpps packet rate I noticed packet drops. I heard and read DPDK can handle millions of packets but in my case, it's not true. In guest, I am using virtio-net which processes packets in the kernel so I believe my bottleneck is my guest VM.
I don't have any guest-based DPDK application like testpmd etc. Does that mean OVS+DPDK isn't useful for my cloud? How do I take advantage of OVS+DPDK with a general-purpose workload?
We have our own loadtesting tool which generate Audio RTP traffic which is pure UDP based 150bytes packets and noticed after 200kpps audio quality go down and choppy. In short DPDK host hit high PMD cpu usage and loadtest showing bad audio quality. when i do same test with SRIOV based VM then performance is really really good.

[Answer] this observation is not true based on the live debug done so far. The reason as stated below
- qemu launched were not pinned to specific cores.
- comparison done against PCIe pass-through (VF) against vhost-client is not apples to apples comparison.
- with OpenStack approach, there are at least 3 bridges before the packets to flow through before reaching VM.
- OVS threads were not pinned which led to all the PMD threads running on the same core (causing latency and drops) in each bridge stage.
To have a fair comparison against SRIOV approach, the following changes have been made with respect to similar question
