kandi X-RAY | profiler Summary
The Firefox Profiler visualizes performance data recorded from web browsers. It is a tool designed to consume performance profiles from the Gecko Profiler but can visualize data from any profiler able to output in JSON. The interface is a web application built using React and Redux and runs entirely client-side. Mozilla develops this tool to help make Firefox silky smooth and fast for millions of its users, and to help make sites and apps faster across the web.

QUESTION
I am fairly new to Tensorflow and I am having trouble with Dataset. I work on Windows 10, and the Tensorflow version is 2.6.0 used with CUDA. I have 2 numpy arrays that are X_train and X_test (already split). The train is 5Gb and the test is 1.5Gb. The shapes are:
X_train: (259018, 30, 30, 3),
Y_train: (259018, 1),
I create Datasets using the following code:
...ANSWER
Answered 2021-Sep-03 at 09:23That's working as designed. from_tensor_slices is really only useful for small amounts of data. Dataset is designed for large datasets that need to be streamed from disk.
The hard way but ideal way to do this would be to write your numpy array data to TFRecords then read them in as a dataset via TFRecordDataset. Here's the guide.

The easier way but less performant way to do this would be Dataset.from_generator. Here is a minimal example:

QUESTION
I have implemented a Convolutional Neural Network in C and have been studying what parts of it have the longest latency.
Based on my research, the massive amounts of matricial multiplication required by CNNs makes running them on CPUs and even GPUs very inefficient. However, when I actually profiled my code (on an unoptimized build) I found out that something other than the multiplication itself was the bottleneck of the implementation.
After turning on optimization (-O3 -march=native -ffast-math, gcc cross compiler), the Gprof result was the following:
Clearly, the convolution2D function takes the largest amount of time to run, followed by the batch normalization and depthwise convolution functions.
The convolution function in question looks like this:
...ANSWER
Answered 2022-Mar-10 at 13:57Looking at the result of Cachegrind, it doesn't look like the memory is your bottleneck. The NN has to be stored in memory anyway, but if it's too large that your program's having a lot of L1 cache misses, then it's worth thinking to try to minimize L1 misses, but 1.7% of L1 (data) miss rate is not a problem.
So you're trying to make this run fast anyway. Looking at your code, what's happening at the most inner loop is very simple (load-> multiply -> add -> store), and it doesn't have any side effect other than the final store. This kind of code is easily parallelizable, for example, by multithreading or vectorizing. I think you'll know how to make this run in multiple threads seeing that you can write code with some complexity, and you asked in comments how to manually vectorize the code.
I will explain that part, but one thing to bear in mind is that once you choose to manually vectorize the code, it will often be tied to certain CPU architectures. Let's not consider non-AMD64 compatible CPUs like ARM. Still, you have the option of MMX, SSE, AVX, and AVX512 to choose as an extension for vectorized computation, and each extension has multiple versions. If you want maximum portability, SSE2 is a reasonable choice. SSE2 appeared with Pentium 4, and it supports 128-bit vectors. For this post I'll use AVX2, which supports 128-bit and 256-bit vectors. It runs fine on your CPU, and has reasonable portability these days, supported from Haswell (2013) and Excavator (2015).
The pattern you're using in the inner loop is called FMA (fused multiply and add). AVX2 has an instruction for this. Have a look at this function and the compiled output.
QUESTION
Using the profiler on SQL Server to monitor a stored procedure call via DBI/odbc, shows that dynamic SQL / prepared statement is generated :
ANSWER
Answered 2022-Feb-16 at 22:26I found what I was looking for in odbc package documentation : direct execution.
The odbc package uses Prepared Statements to compile the query once and reuse it, allowing large or repeated queries to be more efficient. However, prepared statements can actually perform worse in some cases, such as many different small queries that are all only executed once. Because of this the odbc package now also supports direct queries by specifying
immediate = TRUE.
This will use a prepared statement:

QUESTION
In the "React Developer Tools" extension, a profiler has been added that displays the time spent on rendering. Are there any guidelines/table? For example, an acceptable render time for an average web application should be 50-300ms. Or like performance index in chrome developer tool?
...ANSWER
Answered 2022-Feb-07 at 13:10In generally, render should take about 16 milliseconds. Any longer than that and things start feeling really janky.

QUESTION
I have a simple Table created in Azure SQL Database
...ANSWER
Answered 2022-Jan-14 at 18:33From what you have shared here I assume the delay is in network latency.
Dev Java App to Dev Server takes 6 seconds.
Azure Kubernetes App to Azure SQL Database takes 30 ms. Which I think is reasonable if you include the network latency between app and server. I dont think you will get result in 2 ms. If you get, please let me know ;)
Try to check network latency in some ways like doing on SELECT 1 query and calculate turnaround time.
