Detailed summary
The search confirmed that increased search query time negatively impacts user experience and behavior, with users showing heightened sensitivity to delays beyond certain latency thresholds, leading to changes in click behavior, reduced engagement, and satisfaction [1, 2, 6].
Key Findings:User Sensitivity and Behavioral Impact:
- Users are significantly sensitive to response latency, with behavior changing notably when delays surpass specific thresholds (around 200-500 ms reported) [1, 2].
- Increases in query response time are associated with negative shifts in user actions, such as decreased session lengths and click-through rates [1, 2, 5].
Thresholds and Engagement:
- Multiple studies have established that user satisfaction degrades noticeably beyond latency thresholds, with users abandoning slower systems for faster alternatives [2, 3, 6].
- Physiological responses such as frustration and cognitive load increases are reported even with minor delay increments [6, 8].
Empirical Methods:
- Controlled user studies and large-scale log analyses provide robust insights into how response time directly affects user behaviors across varied contexts, including mobile and desktop environments [1, 2, 8].
These findings highlight the critical importance of maintaining low latency in online search systems to sustain user engagement and satisfaction, while pointing to opportunities for further research into adaptive systems and user-specific tolerance thresholds.

Timeline and citation network
Early Foundations (2000-2008):
- Initial studies, such as by Hoxmeier and Dicesare (2000) [16], begin exploring the impact of system response time on user satisfaction, noting dissatisfaction with increased response time. This set the stage for identifying thresholds of acceptability.
- Brutlag et al. (2008) [3] expand by empirically comparing user preferences for fast vs. slow search engine latencies, establishing more concrete insights into user sensitivity and behavior changes, such as abandonment of slower systems.
Advancing Methodologies and Theories (2014-2017):
- Arapakis et al. (2014) [2] and Bai et al. (2017) [1] contribute significantly through controlled user studies and log analyses, illustrating the thresholds of latency that affect user satisfaction and click behavior.
- Maxwell and Azzopardi (2014) [5] introduce Information Foraging and Search Economic Theories to examine search behavior under latency, providing deeper theoretical frameworks.
Exploring Cognitive and Emotional Effects (2015-2016):
- Barreda-Ángeles et al. (2015) [6] delve into physiological and emotional responses to latency, uncovering nuanced attentional and emotional shifts even with minor delays.
- Research in 2016 [10][15] extends to assessing time constraints and delays, diversifying focus to cognitive and task performance impacts under structured conditions.
Nuanced Contextual Analyses (2016-2021):
- Studies like Burton and Collins-Thompson (2016) [7] and Arapakis et al. (2021) [8] refine understanding by focusing on user adaptability in slow search scenarios and mobile vs. desktop latency tolerances, highlighting situational variances in user behavior.
