Job board software speed test

Each platform was measured with Google PageSpeed Insights against a live job board built on it by a real customer, not the platform's own marketing website. That distinction is the whole point of the test: a vendor's homepage is a static marketing page, while the thing you are buying is a job board with search, filters and hundreds of listings on it. Both the Mobile and Desktop tabs were recorded, along with the Core Web Vitals assessment from Chrome field data where enough of it existed. The tests were run 2026-06-08 to 2026-06-09.

Because a platform does not have one speed, it has a range, and the operator controls part of it. Any board can be slowed down by a heavy hero image, a tag manager, three tracking pixels and an embedded chat widget. A single snapshot of one live board tells you what that platform tends to produce in practice, which is more useful than a vendor benchmark and less reliable than a fleet average. Read the numbers as a signal, not a verdict, and click through to the tested board to see what you are looking at.

17 of the 30 platforms in our comparison are not in this table. In most cases we could not find a live customer board to test: the platform sells to enterprises whose boards sit behind a login, or the customers it names publicly have since migrated. Rather than test the vendor's marketing site and present that as a board speed, they are listed as untested below. We would rather have a hole in the dataset than a number that measures the wrong thing.

It affects them, but less than most speed articles imply, and more than most operators assume. Core Web Vitals are a ranking signal in Google search and a tie-breaker rather than a lever: a fast page does not outrank a more relevant slow one. Where speed bites hardest on a job board is crawling and conversion. A board with thousands of listings has a crawl budget, and slow responses mean fewer job pages get crawled per visit, which delays new listings appearing. On the candidate side, a five-second load on mobile is where applications get abandoned. Total Blocking Time is the metric to watch on job boards specifically, because search and filter interfaces tend to ship a lot of JavaScript.

Twice a year, and the date on each row says when it was last measured. Platforms ship changes and customer boards change hands, so a score from eighteen months ago is not evidence of anything. If a row here is stale by that standard, treat it as unmeasured. We would rather publish a small honest table than a large stale one.

You should discount it, and here is what to check. Every row names the exact board that was tested and links to it, and every row links to the PageSpeed screenshot, so any number here can be reproduced in about thirty seconds by running the same URL yourself. The tested Kardow board is a customer board with real traffic and real listings, chosen the same way as the others, not a stripped-down demo. Kardow does not win every metric in this table and the losses are shown rather than omitted.
