Question #268157 on Graphite changed: https://answers.launchpad.net/graphite/+question/268157
Jason Stangroome posted a new comment: I researched this recently. Most (all?) Carbon-Cache and Graphite-Web access to Whisper files is through `whisper.py` which does not specify a buffer size parameter to any file `open` calls. Hence it will be using the Python-implementation default buffer size, which in the particular flavour of CPython I investigated appeared to be 8KiB but could vary across OSes and other Python implementations. It appears that it would be a small PR to support optionally configuring Whisper to use an explicit buffer size in the few places in the code that a file is opened. I personally investigated the block size used in respect to Amazon EBS IOPS but ultimately found that enabling Whisper's Autoflush setting in Carbon Cache gave enough write performance benefit to not need to follow up further. -- You received this question notification because you are a member of graphite-dev, which is an answer contact for Graphite. _______________________________________________ Mailing list: https://launchpad.net/~graphite-dev Post to : graphite-dev@lists.launchpad.net Unsubscribe : https://launchpad.net/~graphite-dev More help : https://help.launchpad.net/ListHelp
