response-time

问题 this will be a very baic question since im new to Spring-Redis Im currently in the process of learning about Redis database and I'm working on a feature on priority, im compelled to Use Redis for this feature. Below in the challenge/Query im having. Right now we have a DataModel as below: @RedisHash("Org_Work") public class OrgWork { private @Id @Indexed UUID id; private @Indexed String CorpDetails; private @Indexed String ContractType; private @Indexed String ContractAssigned; private

问题 I'm executing performance testing using JMeter and Blazemeter report, but the response time value is the same as latency time value. can somebody explain? I attach the graph results: Latency Time Graph Response Time Graph 回答1: It just means that the response is small/empty. The values are TTLB and TTFB, See explanantion about the difference Latency is a difference between time when request was sent and time when response has started to be received . Response time (= Sample time = Load time =

问题 I'm looking into the possibility to use BigQuery and its API to do on-site queries depending on content that is viewed by our visitors. Therefore the response time is crucial. I have loaded a very simple structured dataset of 10k rows (4columns) and run a very simple query and that takes between 1 and 2 seconds. My questions is hopefully pretty simple to answer, will I ever be able to get a <1sec response time with the BQ API by optimising the data in someway or not? Thanks a lot in advance!

问题 my average response time is coming greater than the 99 percentile( in JMeter). 回答1: So what? My too. This is normal situation when you have: low number of samplers with high response time and high number of samplers with low response time In above setup I used 1 Dummy Sampler with 1000 milliseconds response time and 100 Dummy Samplers with 1 millisecond response time resulting in average response time of 11 ms and 99% of 4 ms.

问题 We have a client and a server. I want to measure the response-time of the network between them. When I send a request to server it should immediate respond to my request, it should be like a ping request so that there will be no processing time at the server. How can I do this in Java? 回答1: I have done this by sending a packet with a timestamp from client to server, and then having the server return the same timestamp back. When the server receives the timestamp, it can compare against the

问题 I have a web server running inside a docker container in AWS EC2 Ubuntu instance. When I send requests to the web server, I get the response very slowly (20+ seconds most of the times, although the response time varies). It does not time-out though . The web server is a very lightweight. It is only to test, so almost does not do anything. docker version 17.03.0-ce docker-compose version 1.12.0-rc1 How I debugged so far When sending requests to the web server running in the docker container

问题 Does anyone have links to current and historical papers and authoritative links (statistics and blog posts) regarding response-time for user interfaces? Naturally the authoritative link is Human factors design criteria in man-computer interaction Some key quotes include: [Regarding] response to request for next page. […] Delays of longer than 1 second will seem intrusive on the continuity of thought. And Assume an inquiry of any kind has been made. The user – and his attention – is captive to

问题 I ran a JMeter test for 193 samples where I could see my average response time as 5915ms and Throghput as 1.19832. I just want to know how are they exactly related 回答1: TL;DR No, but yes. Both aren't related directly, but when increasing Throughput, it will probably effect server response time due to load/stress on server. If there are timeout errors response time will probably increase. But for validation or firewall errors - response time will probably decrease. There's a long explanation

问题 A delay will always occur between a user action and an application response. It is well known that the lower the response delay, the greater the feeling of the application responding instantaneously. It is also commonly known that a delay of up to 100ms is generally not perceivable. But what about a delay of 110ms? What is the shortest application response delay that can be perceived? I'm interested in any solid evidence, general thoughts and opinions. 回答1: What I remember learning was that
