Faidon Liambotis <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #18 from Faidon Liambotis <[email protected]> --- Can we have some numbers showing the performance & bandwidth effect that ULS has, both from the client-side performance perspective, as well as from the backend performance (mostly bandwidth, I assume)? Similarly, can we get some hard numbers on the benefit that ULS has (presumably, % of users)? Quantifying this would personally help me understand the feature better and have a more informed opinion. I know that e.g. the extra bandwidth can be detrimental on users' usage in some countries, the extra page latency (load performance) has been directly correlated to user retention by multiple studies and the extra CPU & bandwidth can be directly mapped to an increase in operational costs (very rough calculations of the bandwidth cost of ULS for the interlanguage links as deployed between July-September was 40-50k USD). On the flip side, I'm sure there are arguments about e.g. user/editor retention in favor of ULS. I don't know much about them, but I'd certainly like to hear more as I currently have a skewed perception of the issue; pointers welcome. In the end, we have to make a comparison of what we gain and what we lose in each case, evaluate the tradeoff and possibly compromise. It is my opinion that this case has to be made by the people wishing to *enable* this feature, not by the ones arguing to disable it. We can't make this the single performance engineer's problem (or, similarly, ops' problem) and ask them to make the comparative analysis for every single feature that is being developed & deployed in production. Since this has been clearly controversial and has produced issues in the past, and until we do have such a preliminary analysis, it is also my opinion that we need to temporarily disable ULS in production or at least limit its deployment considerably (e.g. only small non-Latin wikis and/or beta features). -- You are receiving this mail because: You are the assignee for the bug.
