We have a product that contains about 50 assemblies (DLL files), most of which are required and loaded when the main executable file starts. The result is even on a medium-speed machine , The load
Category: Performance
Whether you are a system designer, developer or tester, to build a high-performance system, you need to understand the following concepts: 1. Response time is the time for the system to respond to user requests, and response time is the user’s most intuitive experience of system performance. Therefore, the performance of the system is directly expressed. 2. Concurrent users, within a certain time frame, the largest number of simultaneous online users, that is, the number of peak online users 3. System throughput refers to the number of requests processed by the system within a unit time 4. Think Time, From a business perspective, this time refers to the time interval between each request when the user performs an operation. In order to simulate this time interval during performance testing, the concept of thinking time is introduced to more realistically simulate the user’s operate. In the formula of throughput, F=VU * R / T shows that throughput F is a function of the number of VUs, the number of requests issued by each user R, and time T, and R can be calculated by time T and user thinking time TS Calculation: R = T / TS
Performance – Oracle: Executive Plan: Is it reliable?
Please see the execution plan below.
It says that Oracle will start from the index range scan…
But it’s impossible because it doesn’t have any values to look up, Because it reads these values
Performance – Why is Cassandra secondary index on 350K lines so slow?
I have a column family with a secondary index. The secondary index is basically a binary field, but I am using a string. The field named is_exported can be “true “Or “false”. After the request, all

Is over-image cutting cause a deep learning model in a poor performance?
I’m currently building a deep learning model to recognize images. According to my reading, data addition (such as randomly cropping images) will reduce the model’s overfitting. However, I’m not sur
