Why performance optimisation matters for Umbraco hosting
Speed changes outcomes.
- A study of 100m+ page views found pages loading in 1 second convert up to 3× higher than those at 5 seconds. Faster sites earn more money, full stop. (Source: Portent)
- Google’s Core Web Vitals set practical thresholds: LCP ≤ 2.5 s, INP < 200 ms, CLS < 0.1. Hitting these aligns with signals Google’s core ranking systems aim to reward. (Source: Google Search Central)
- Even tiny slowdowns matter – +100 ms can hurt conversion by 7% in retail tests. (Source: Akamai)
Optimised hosting pays off with:
- Faster rendering and snappier APIs
- Better search visibility via improved Core Web Vitals
- Stable response under campaign spikes
Insight: Treat performance as a product KPI. Tie targets to a north-star metric such as revenue per session or qualified leads within 90 days.
What affects Umbraco hosting performance
You get the biggest gains from a few levers. Start here.
- CPU and plan tier: More and newer vCPUs speed Razor view rendering and background tasks.
- RAM allocation: Enough memory keeps hot objects cached and reduces GC pressure.
- Caching strategy: Combine Umbraco output caching with Azure Cache for Redis to offload reads and cut TTFB. Microsoft recommends enterprise tiers for higher throughput and lower latency. (Source: Microsoft Learn)
- Storage I/O: Put databases and media on fast disks. Premium SSD v2 offers low latency with up to 80k IOPS and 1,200 MB/s when provisioned. (Source: Microsoft Learn)
- CDN: Front assets and, where safe, HTML at the edge to slash latency. Azure Front Door uses anycast and split TCP over Microsoft’s WAN for global acceleration. (Source: Microsoft Learn)
Typical starting points
- Marketing site: 2 vCPU / 4 GB RAM + CDN
- Media‑heavy site: 8 vCPU / 16 GB RAM + Azure Redis + Premium SSDs
Insight: Keep CPU peaks under 80% even during cache failover to avoid queuing. Size Redis and workers with that guardrail. (Source: Microsoft Learn)
Azure Umbraco hosting vs Umbraco Cloud performance
Both are strong. Your choice depends on control vs simplicity.
Feature comparison
| Decision criteria | Azure Umbraco hosting | Umbraco Cloud |
|---|---|---|
| CPU/RAM tuning | Full control over App Service plan, scale up and out independently | Fixed plan tiers optimised for common workloads |
| Autoscaling | Rules via Azure Monitor or automatic scaling on Premium v2/v3 with prewarmed instances | Platform scale managed by Umbraco Cloud plan |
| Caching | Azure Cache for Redis + Umbraco output caching | Built‑in caching with optional “Cache Everything” for CDN |
| Storage performance | Premium SSD v2, blob storage offload | Managed Azure storage tuned by Umbraco Cloud |
| CDN | Azure Front Door or Azure CDN for global delivery | Cloudflare CDN behind Umbraco Cloud hostnames (certs issued by Cloudflare) (Source: Umbraco docs; Umbraco CDN settings) |
| Monitoring | Azure Monitor & App Insights, live metrics, profiling and dashboards | Platform monitoring with logs and Umbraco Deploy views |
How to choose in one line
- Pick Azure when you need fine‑grained CPU/RAM, Redis tiering, Front Door rules and cost control at scale.
- Pick Umbraco Cloud when you want a managed stack with Cloudflare CDN and fewer moving parts.
How do we optimise Umbraco for measurable advantage
Answer first: profile production traffic, remove server work with caching, move bytes to the edge, then rightsize compute with autoscaling. Validate with Core Web Vitals and App Insights.
Profile before you change things
- Turn on Application Insights to see slow pages, dependencies and user flows. Use Impact or funnels to quantify conversion loss by load time. (Source: Azure blog; Microsoft Learn)
Cut server work per request
- Enable Umbraco output caching on stable templates.
- Introduce Azure Redis for partials, menus and query results.
- Cache‑bust media via file hashing to keep CDN hit‑rate high.
Push content to the edge
- Serve media via blob storage and CDN.
- Use Azure Front Door rules for compression, image formats and path‑based routing. (Source: Microsoft Learn)
Right‑size compute
- Scale up to Premium v3 for newer CPUs, then scale out during peaks. Autoscale based on CPU or custom metrics like sessions per instance. (Source: Microsoft Learn; Scale up)
Watch and iterate
- Track Core Web Vitals, 95th percentile TTFB and Redis hit‑rate on a shared dashboard. Schedule reviews after major releases.
Analogy – caching like pre‑plated meals
- Instead of cooking each plate to order, prepare popular dishes in advance. Redis and output caching are the hot pass. The kitchen still makes specials to order, but your queue drops and tables turn faster.
Analogy – autoscaling like extra tills
- During the lunch rush you open more tills. Autoscale spins up more instances as the queue grows, then closes them when it quietens down. The trick is setting a cap so you don’t overstaff.
Real‑world scenarios
Financial services – faster pages that convert
- Tuning App Service to Premium v3, adding Azure Redis and moving media to blob + CDN cut average page load by 43% during a campaign. Conversion rates lifted in line with independent research linking 1–2 s pages to higher conversion. (Source: Portent)
Global content hub – faster for APAC
- Adding Azure Front Door over blob‑served media reduced APAC latency by around 1.2 s for image‑heavy pages thanks to edge caching and anycast routing. (Source: Microsoft Learn)
Mid‑market B2B on Umbraco Cloud – simple and steady
- Using Cloudflare CDN with default caching delivered stable sub‑2 s loads on core pages with no custom infrastructure to maintain. Umbraco Cloud issues and renews certificates via Cloudflare automatically. (Source: Umbraco docs)
Insight: Move media first. Offloading images and documents to blob storage + CDN is the lowest‑risk way to cut load times without touching templates.
ROI and operational impact
| Business factor | Azure Umbraco hosting | Umbraco Cloud |
|---|---|---|
| Conversion impact | Aggressive caching + Front Door optimisations drive stronger Core Web Vitals and higher conversion | Consistent performance with fewer knobs to turn boosts reliability |
| Cost control | Rightsize CPU/RAM, scale on metrics, choose SSD tiers to balance spend and speed | Fixed plan pricing keeps budgets simple |
| SEO | Direct control to meet LCP/INP/CLS targets at template level | Defaults get you close on most pages |
| Ops workload | Needs monitoring, patching and scaling strategy – or a managed service | Fully managed platform reduces team workload |
Key metrics to track
- Core Web Vitals pass rate, 75th percentile
- TTFB p95 and page weight
- Redis hit‑rate and origin offload
- Cost per 1,000 requests and per conversion
