Impact of response latency on user behavior in web search
2014
Proceedings of the 37th international ACM SIGIR conference on Research & development in information retrieval - SIGIR '14
Preserved Fulltext
Second, we perform an analysis using a large-scale query log obtained from Yahoo web search to observe the potential impact of increasing response latency on the click behavior of users. ...
However, an in-depth analysis on the interplay between the response latency of web search systems and users' search experience has been missing so far. ...
CONCLUSIONS We investigated the impact of increasing response latencies on user behavior in web search. ...

Using web search as an exemplary case study, our detailed measurements reveal that a vanilla TCP splitting solution deployed at the satellite DCs reduces the 95 th percentile of latency by as much as 43% ...
Through careful dissection of the measurement results, we characterize how individual components, including proxy stacks, network protocols, packet losses and network load, can impact the latency. ...
Impact of Proxy OS: In the course of our experiment, we found that the operating systems on the proxies have a large impact on the latency, as they exhibit very different TCP window behavior. ...

Search result examination is an important part of searching. High page load latency for landing pages (clicked results) can reduce the efficiency of the search process. ...
Balancing the costs in prefetching particular results against the benefits in reduced latency to searchers represents the search result prefetching challenge. ...
The remainder of this paper is structured as follows. Section 2 describes related work in areas such as prefetching, the impact of response latency on user engagement, and mouse cursor monitoring. ...

On Earth, users are accustomed to nearly instantaneous responses from web services. Is it possible to overcome orders-of-magnitude longer latency to provide a tolerable user experience on Mars? ...
In this paper, we formulate the searching from Mars problem as a tradeoff between "effort" (waiting for responses from Earth) and "data transfer" (pre-fetching or caching data on Mars). ...
To simulate the impact of caching pages on Mars, we require some assumptions about user behavior in addition to the actual behavior captured in the log. ...

Research suggests that even slightly higher retrieval latency by Web search engines can lead to dramatic decreases in users' perceptions of result quality and engagement with the search results. ...
While users have come to expect rapid responses from search engines, recent advances in our understanding of how people find information suggest that there are scenarios where a search engine could take ...
To further understand how query task impacts behavior, we look at the impact that search engine response time has for navigational and informational query types. ...

In this paper, we perform a measurement study of a popular, large scale web-QA system, i.e. iAsk, and systematically investigate various behavior patterns and the system performance. ...
The framework reveals that the QoS of a web-QA system actually heavily depends on three key factors: the user scale, user reply probability and a system design artifact (related to webpage layout). ...
Therefore, user behavior have a profound impact on the QA system's performance. A good understanding of user behavior will provide meaningful hints for improving the web-QA system. ...

User-perceived latency is recognized as the central performance problem in the Web. We systematically measure factors contributing to this latency, across several locations. ...
We chose to focus on these requests since search-engines and Web-portals sites typically invest considerable effort to provide low-latency high-quality service. ...
