Although I agree with the others here that memcache can very well be slower than cached local file access, and that sounds like *part* of your issue. But your failed requests concern me. More details would be extremely helpful.
1. How large is the file/data you are caching, and exactly how are you caching it? 2. How are you determining failure? 3. If you write a test script with a bunch of arbitrary sets and then gets of the same keys, do they fail? Jay
