Hello, We've being performing some cache tests and noticed two issues that we would like to check with the community:
1. The interim cache is limited to the same size as the RAM cache, no matter how big the partition allocated to it is. 2. Whenever a volume gets full and the write head begins writing to the volume's start again, the RAM cache gets unused for a while, and requests that could be served from RAM get served from the storage. Notice that we considered the possibility that the objects that we _thought_ were in the RAM had been replaced, but even requesting the same set of objects a few times would not make them be served from the RAM. Are these statements correct? We came to them based on observations made during the tests fully described on [1]. We hope there's enough information on the document to reproduce the tests. We're available should someone need more info about our test scenarios. Feel free to contact me or Daniel Biazus at daniel.bia...@azion.com .
