High performance querying of data in Umbraco V8 BY PAUL SEAL AND TIM PAYNE
Paul Seal - from Moriyama @CodeSharePaul Tim Payne @attack_monkey
What are we talking about? A bit of history Performance in V7 Changes in V8 Performance in V8 Caching! Conclusions
Content internals fairly consistent from V4 - 7 Content was cached in the umbraco.config XML file Various APIs sat on top (more added for V6/7) Early days were XSLT and Node based Razor and dynamics added in V6 Strongly typed models added later Examine/Lucene support too
By the end of V7 we have MANY APIs Document API Node API Dynamic Content (also query by XSLT) Typed Content (also query by XSLT) Content Service Examine TypedSearch Umbraco.library (mostly XSLT)
Built a V7 website, 5000 articles, selected everything!
Conclusions for V7 Friends don t let friends use the content service on the front end XPath/XSLT methods are all VERY fast for simple cases LINQ fine if used wisely Examine the best method for any meaningful searching/sorting
Content is now stored in a binary cache called NuCache (lives in /App_Data/TEMP/NuCache) Content API surface GREATLY reduced Content Service Typed Content (can still use XPath) Examine (new version, woohoo)
Interesting notes XPath only made to work for MNTP Every time NuCache is queried, it caches that query in memory There is a NuCache explorer tool which lets you view the NuCache files as JSON There is a V8 package called Our.Umbraco.NuCacheExplorer which lets you view the NuCache files from the backoffice.
Built a V8 website Installed Clean Starter Kit Created 5000 articles Got average times from running each Query Method 1000 times
What we noticed in V8 All of the V8 API methods of searching are way faster than in V7. If you are getting all/latest then it s faster to use the LINQ methods. Examine will perform better on more complicated searches. XPath is surprisingly fast.
Caching Code @using Umbraco.Core.Cache Pass in AppCaches to your constructor, give access to both the Runtime cache and the Request cache Use GetCacheItem extension and pass in function used to hydrate: caches.RuntimeCache.GetCacheItem( latestNews , () => MyService.GetLatestArticles()); To clear the cache item (say on publish): caches.RuntimeCache.ClearByKey( latestNews ); Other methods of clearing are available!
Conclusions LINQ MUCH faster in V8 Examine is still good for searching. More content = be more careful with LINQ XPath sort of works but is not meant to be used in V8 anymore Caching is good but mainly worth it if you are converting the data to models etc.
