Explains the difference between minification and compression, details the Brotli compression algorithm versus gzip (compression levels, default settings, browser support), and contrasts ASP.NET Core's in-process vs out-of-process hosting models with Kestrel. Also introduces MiniProfiler as a tool for profiling specific code sections across .NET, Go, Ruby, and Node.js. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What's the difference between Brotli and gzip compression for web performance? Brotli, developed by Google, achieves smaller file sizes than gzip, around 17% better compression, using a shared dictionary between client and server to replace common keywords with smaller keys. Gzip's compression levels range from 1 to 9 with a default of 6, while Brotli ranges from 1 to 11 with a default of 11, making it slower by default but more compressed. Brotli is supported by nearly all browsers except IE11. _daily.dev surfaces practical comparisons like this for developers tuning web response times._ ### Should I use in-process or out-of-process hosting model for ASP.NET Core on IIS? In-process hosting model is faster because the app runs in the same process as the IIS worker, avoiding the extra HTTP call to Kestrel that out-of-process hosting requires. Out-of-process is the default for .NET Core apps due to cross-platform design, but on Windows machines you should switch to in-process by setting AspNetCoreHostingModel to InProcess in web.config. _Developers tuning ASP.NET Core deployments on IIS can find configuration guidance like this via daily.dev._ ## Similar posts on daily.dev - [Performance Tuning in ASP.NET Core: Best Practices for 2025](https://daily.dev/posts/performance-tuning-in-asp-net-core-best-practices-for-2025-ffdkptjfa) · Syncfusion · 3 upvotes · 0 comments - [Web Performance & Optimisation](https://daily.dev/posts/web-performance-optimisation-i331jarhz) · Medium · 2 upvotes · 0 comments - [ASP.NET Core 11 Request Pipeline Performance Deep Dive](https://daily.dev/posts/asp-net-core-11-request-pipeline-performance-deep-dive-y8dxv0kx8) · C\# Corner · 2 upvotes · 0 comments - [Web Performance 2025: The Shift from Optimization to Prediction](https://daily.dev/posts/web-performance-2025-the-shift-from-optimization-to-prediction-emdlyovyv) · Web Performance Calendar · 0 upvotes · 0 comments - [A complete guide to React performance optimization](https://daily.dev/posts/a-complete-guide-to-react-performance-optimization-zei2krfdt) · LogRocket · 3 upvotes · 0 comments --- Tags: [#performance](https://daily.dev/tags/performance), [#aspnet](https://daily.dev/tags/aspnet) [View this post on daily.dev](https://daily.dev/posts/a-few-tips-for-performance-optimization-ltaspwqpe) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"A few tips for performance optimization","url":"https://daily.dev/posts/a-few-tips-for-performance-optimization-ltaspwqpe","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/a-few-tips-for-performance-optimization-ltaspwqpe"},"datePublished":"2026-10-04T13:06:48.722Z","dateModified":"2026-10-04T13:09:59.055Z","description":"Covers several techniques for improving website loading speed, including splitting JS/CSS into chunks, compressing content, using CDNs, and geographic...","image":"https://media.daily.dev/image/upload/s--P4t4XyoV--/f_auto/v1722860399/public/Placeholder%2001","thumbnailUrl":"https://media.daily.dev/image/upload/s--P4t4XyoV--/f_auto/v1722860399/public/Placeholder%2001","isAccessibleForFree":true,"articleSection":"Code4IT","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Code4IT","logo":"https://media.daily.dev/image/upload/s--OaaG4G10--/f_auto,q_auto/v1791119049/logos/code4it?_a=BAMAMicg0","url":"https://daily.dev/sources/code4it"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/a-few-tips-for-performance-optimization-ltaspwqpe","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"performance,aspnet","timeRequired":"PT5M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Code4IT","item":"https://daily.dev/sources/code4it"},{"@type":"ListItem","position":3,"name":"A few tips for performance optimization"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/a-few-tips-for-performance-optimization-ltaspwqpe#faq","mainEntity":[{"@type":"Question","name":"What's the difference between Brotli and gzip compression for web performance?","acceptedAnswer":{"@type":"Answer","text":"Brotli, developed by Google, achieves smaller file sizes than gzip, around 17% better compression, using a shared dictionary between client and server to replace common keywords with smaller keys.
