Every bit of paper that comes into my house immediately gets scanned on my phone and entered into my account, where its accessible from my phone. That includes email attachments like PDFs, notes from meetings, invoices, medical bills, etc. No matter where I am, I can easily lookup that account number or receipt without needing paper or a laptop.  I happily paid the yearly fee as it increased over that time, but two years ago Evernote was purchased by Bending Spoons, an EU-based … Continue reading »]]> https://www.webperformance.com/load-testing-tools/blog/2025/12/load-tester-6-9-new-interactive-dashboard-massively-faster-correlation-new-regions/ Sun, 07 Dec 2025 18:57:40 +0000 https://www.webperformance.com/load-testing-tools/blog/?p=6465 Continue reading »]]> https://www.webperformance.com/load-testing-tools/blog/2025/10/wploadanalyzer-ai-beta-release-available-for-download/ Thu, 23 Oct 2025 18:06:18 +0000 https://www.webperformance.com/load-testing-tools/blog/?p=6460 Continue reading »]]> https://www.webperformance.com/load-testing-tools/blog/2025/07/announcing-load-tester-6-8/ Tue, 15 Jul 2025 22:37:17 +0000 https://www.webperformance.com/load-testing-tools/blog/?p=6442 Understanding Web Pages in Modern Web Apps, it can be difficult to figure out the definition of a “web page” in modern apps.

I have been using it recently to store load-test measurements created by the MuseIDE Measurements extension. I have been running it in the cloud, starting up a fresh instance whenever I have the need for storing load test results.
