Performance crime: config to kill performance
Would you as a developer allow a setting that can make system 15 550 times slower? I’ve received a few memory dumps with high CPU; each scavenges AccessResultCache: How big is the cache so that every snapshot contains the operation? Detecting cache size from the snapshot A ClrMD code snippet locates objects in Sitecore.Caching.Generics.Cache namespaceContinue reading “Performance crime: config to kill performance”

Performance crime: wrong size detection
The amount of memory cache can use is defined in config: That is needed to protect against disk thrashing – running out of physical RAM so that disk is used to power virtual memory (terribly slow). That is a big hazard in Azure WebApps – much less RAM compared to old-school big boxes. Sitecore keepsContinue reading “Performance crime: wrong size detection”
