Scaling a WooCommerce website for a global brand without breaking a sweat

⚠️ The Challenge

For 11 months of the year, their website runs at a steady, resource-intensive pace — managing orders, shipping, wholesale pricing, and multi-region content.

But for 1 month of the year, all that changes.

Their flagship annual sale drives a surge in traffic up to 100x normal levels. It’s the biggest event of their calendar — and it had a history of crashing their site.

🚫 Previous Hosting Pain (on Kinsta)

• Even on Kinsta’s largest plan, the site crashed during sale events.

• Despite caching, every visitor triggered dynamic requests, bypassing the cache.

• Their site adjusted prices and shipping dynamically based on the visitor’s location, which meant the server re-generated each page per visitor, leading to overload.

• During the sales event they can have 5,000+ concurrent PHP users active which would break the site — costing sales, trust, and sanity.

🔍 The Staq Solution

We performed a full performance audit and found the issue: the dynamic currency and location detection logic was preventing effective caching.

✅ Our Approach:

• We implemented a dynamic caching layer using Staq Cache.

• With a simple but effective script, we detected each visitor’s location (via IP or cookie) and cached a page specific to their country and currency.

• This allowed the site to serve cached pages instead of re-rendering dynamically each time, even during massive traffic spikes.

🚀 Instant Results:

• Visitors still saw their local currency (e.g. AUD, USD, EUR), but the site no longer needed to generate the page each time.

• Performance soared. Crashes stopped.

• The team could finally run sale events without technical stress.
