If you judge a proxy trial by the fastest screenshot, you can end up choosing the more expensive option in practice. A pool that looks quick but fails too often creates retry waste, longer job windows, and noisier operations.<\/p>\n

The better rule is this: success rate should usually decide the trial first, and speed should break ties only after reliability is already good enough<\/strong>.<\/p>\n

Use this table first when comparing trial results<\/h2>\n

Why success rate usually matters more than raw speed<\/h2>\n

A fast request is only useful if it actually finishes the job. During a trial, buyers often compare median response time first because it is easy to measure. The problem is that raw speed rarely captures the full operating cost of a weak pool.<\/p>\n

When a proxy plan fails more often, you pay for it in four places:<\/p>\n

    \n
  1. Retry overhead<\/strong>. Extra attempts stretch job duration and make concurrency planning less predictable.<\/li>\n
  2. Operator time<\/strong>. Teams spend longer debugging whether the issue is auth, routing, target sensitivity, or session drift.<\/li>\n
  3. Workflow instability<\/strong>. A pool that is fast on good requests but inconsistent across the whole batch is harder to trust for QA, warm-up, and monitoring.<\/li>\n
  4. Misleading trial conclusions<\/strong>. A small sample of fast wins can hide a bigger pattern of blocks, resets, or incomplete runs.<\/li>\n<\/ol>\n

    For a broader pre-buy framework, see the post on proxy trial checklists<\/a>. If authentication differences are muddying the data, use the proxy authentication checklist<\/a> before blaming the pool itself.<\/p>\n

    When speed should make the final call<\/h2>\n

    Let speed decide when all three conditions are true:<\/p>\n
