Oh, wait, bubble sort is stable so it can't be that. Any other theories?

- anonymfus 8y ago>Any other theories? 1. Excel needs stable sort but OSX sort is unstable. 2. Performance deoptimisation to make Excel perform worse.
- iainmerrick 8y agoThere are any number of better ways to fix 1, though! 2 occurred to me too, but surely that’s too cynical. It would make Macs look bad more than Excel itself. Maybe it’s a bit of both. They needed a fix for 1, but they didn’t care about Excel performance at all so someone just spent 20 seconds doing a quick bodge job.
- saagarjha 8y agoMaybe because the software has a race condition around sorting which requires the use of a slower sort?
- r00fus 8y agoIs it wrong to ask if Microsoft intended it to be slow? Mac Outlook on a recent MBP is noticeably slower (usability impact) than a similar version of Outlook on my Windows VM on the same machine against the same account (30k items, 5GB-ish)
