How often the site is visited from specific place?

Can “site visit frequency from specific place (or better, certain company office)” be just a query away? The needed analytics data is already collected by Sitecore, hence data mining could roughly be: Figure out area postal code (or reverse it by IP using any reverse IP lookup) Find all contacts that have the same detailsContinue reading “How often the site is visited from specific place?”

Case study: polluted reports

Agenda Analytics reports have suspicious statistics with lower conversion rates compared to other systems. Can we find out why? It seem that healthy data is diluted with junk/empty interactions with no value. We assume robot/crawlers activity gets recorded. Is there any OOB protection in Sitecore? Filter out robots by user agents Sitecore blacklists robots viaContinue reading “Case study: polluted reports”

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”

Performance crime: careless allocations

I was investigating Sitecore Aggregation case a time back and my attention was caught by GC Heap Allocation mentioning RequiresValidator in top 10: Combining all generic entries together leads to over 7% of total allocations making it second most expensive type application wide! Yes, all it does is check object is not null Yes, itContinue reading “Performance crime: careless allocations”
