kandi X-RAY | performance Summary
In our work, we will be dealing with the performance and speed optimizations of an underlying server and a WordPress-based website running on it. After a thoughtful study of our work, an ordinary web programmer or administrator will be able to install and configure his web server and refactor the source code of his PHP (WordPress) web application, without having to research what to modify or avoid from other sources, thus saving his time and resources. Product of our work will be a highly optimized server with proper caching and a WordPress website developed to be as efficient as possible.

QUESTION
I am making a simulation with C (for perfomance) that (currently) uses recursion and mallocs (generated in every step of the recursion). The problem is that I am not being able to free the mallocs anywhere in the code, without having the wrong final output. The code consist of two functions and the main function:
evolution(double initial_energy)
ANSWER
Answered 2021-Jun-13 at 04:47You're supposed to free memory right after the last time it will be used. In your program, after the while
loop in recursion
, Energy
isn't used again, so you should free it right after that (i.e., right before return event_counter;
).
QUESTION
I am just curious does batch listener mode in Spring Kafka gives better performance than non-batch listener mode? If we are handling exceptions then we still need to process each record in Batch-listener mode. Non-batch seems less error prone, stable and customizable .
Please share your views on this as I didn't find any good comparison.
...ANSWER
Answered 2021-Jun-15 at 20:19It completely depends on what your listener is doing with the data.
If it processes each record in a loop then there is no benefit; you might as well just let the container iterate over the collection and send the listener one record at-a-time.
Batch mode will improve performance if you are processing the batch as a whole - e.g. a batch insert using JDBC in a single transaction.
This will often run much faster than storing one record at-a-time (using a new transaction for each record) because it requires fewer round trips to the DB server.
QUESTION
I have a store setup that has multiple arrays
I'm trying to search all arrays at once, via a textfield.
I can get this done, by calling a selector function on keyup, that filters the 4 arrays and pushes to a new array.
I've thought about merging all the arrays to one array before filtering, but I want to keep the results separate, as they are going to be displayed in categories.
Just trying to see if I can streamline the performance at all and if there's a more concise way of doing this, in case I need to do something similar with larger arrays.
my textField function:
...ANSWER
Answered 2021-Jun-15 at 19:16This should implement the selector function with less code and make it more adaptable to kinds of data, if needed you can specify a more precise type in the filter function.
QUESTION
Trying to use Impact font in my html email, which is working fine in Outlook 365 windows and web clients, as well as Gmail client in browser, but the iOS native Mail app, Gmail app and Outlook apps all default back to arial. What am I missing?
Here's the table in question. Class is leftover from a MS port, and I'm leaving it in in the hopes that it improves mso performance, but all it's really doing is setting default font-family, font-size and margin (0).
...ANSWER
Answered 2021-Jun-15 at 05:24Impact may not be 'websafe' then, as it appears to NOT be installed on Androids and iOS (mobile), otherwise it would work. Unless the class "MsoNormal" has a different font-family on it. (I would remove that, it's not necessary or related to performance.)
If that fails, you'll need you to use @font-face
to load it in from a public website. Keep in mind @font-face
is not supported on everything: https://www.caniemail.com/features/css-at-font-face/
As a fallback, you might like to use a similar font, via Google Fonts which is already setup for this: https://fonts.google.com/specimen/Anton
But to make it work on absolutely everything, you'll need to save it as an image, and load in as

I've upgraded to the M1 chip 2020 Macbook Air from a 7th gen. Intel chip pc. Overall, I'm very happy and content with it but when it comes to Android Studio performance, which I use quite often, it is very disappointing I'm sorry to say. When will an Apple Silicon compatible version be available? Are any of you guys have any clue?
...ANSWER

I am programming in Python 3.8 with Tensorflow installed along with my natural language processing project. When I want to begin the training phase, I get this message right before I begin...
...ANSWER
Answered 2021-Mar-10 at 14:44I would suggest you to use conda
(Ananconda/Miniconda) to create a separate environment and install tensorflow-gpu
, cudnn
and cudatoolkit
. Miniconda has a much smaller footprint than Anaconda. I would suggest you to install Miniconda if you do not have conda
already.
QUESTION
I have two MLModel
s in my app. The first one is generating an MLMultiArray
output which is meant to be used as the second model input.
As I'm trying to make things as performance-best as possible. I was thinking about using VNImageRequestHandler
to feed it with the first model output (MLMultiArray
) and use Vision
resize and rectOfIntersent to avoid converting the first input to an image, crop features, to avoid the need to convert the first output to image, do everything manually and use the regular image initializer.
Something like that:
...ANSWER
Answered 2021-Jun-15 at 09:01Vision uses images (hence the name ;-) ). If you don't want to use images, you need to use the Core ML API directly.
If the output from the first model really is an image, it's easiest to change that model's output type to an image so that you get a CVPixelBuffer instead of an MLMultiArray. Then you can directly pass this CVPixelBuffer into the next model using Vision.

I am trying to contribute to a Github Page/Jekyll site and want to be able to visualise changes locally but when I run bundle exec jekyll serve
but I get this output:
ANSWER
Answered 2021-Feb-02 at 16:29I had the same problem and I found a workaround here at https://github.com/jekyll/jekyll/issues/8523
Add gem "webrick"
to the Gemfile in your website. Than run bundle install
At this point you can run bundle exec jekyll serve
For me it works!
QUESTION
We are using stream ingestion from Event Hubs to Azure Data Explorer. The Documentation states the following:
The streaming ingestion operation completes in under 10 seconds, and your data is immediately available for query after completion.
I am also aware of the limitations such as
Streaming ingestion performance and capacity scales with increased VM and cluster sizes. The number of concurrent ingestion requests is limited to six per core. For example, for 16 core SKUs, such as D14 and L16, the maximal supported load is 96 concurrent ingestion requests. For two core SKUs, such as D11, the maximal supported load is 12 concurrent ingestion requests.
But we are currently experiencing ingestion latency of 5 minutes (as shown on the Azure Metrics) and see that data is actually available for quering 10 minutes after ingestion.
Our Dev Environment is the cheapest SKU Dev(No SLA)_Standard_D11_v2 but given that we only ingest ~5000 Events per day (per metric "Events Received") in this environment this latency is very high and not usable in the streaming scenario where we need to have the data available < 1 minute for queries.
Is this the latency we have to expect from the Dev Environment or are the any tweaks we can apply in order to achieve lower latency also in those environments? How will latency behave with a production environment loke Standard_D12_v2? Do we have to expect those high numbers there as well or is there a fundamental difference in behavior between Dev/test and Production Environments in this concern?
...ANSWER
Answered 2021-Jun-15 at 08:34Did you follow the two steps needed to enable the streaming ingestion for the specific table, i.e. enabling streaming ingestion on the cluster and on the table?
In general, this is not expected, the Dev/Test cluster should exhibit the same behavior as the production cluster with the expected limitations around the size and scale of the operations, if you test it with a few events and see the same latency it means that something is wrong.
If you did follow these steps, and it still does not work please open a support ticket.
