Microsoft Corp said on Tuesday that software patches released to guard against microchip security threats slowed down some personal computers and servers, with systems running on older Intel Corp processors seeing a noticeable decrease in performance.

The comments in a blog post were the clearest signal from Microsoft that fixes for flaws in microchips from Intel and rivals described last week could meaningfully degrade performance. The topic is of keen interest to large data center operators, which could incur significant cost increases if computers slow down.
