Gantt/timeline app users: has slowness ever actually made you switch apps?

[黄雍蓉]

 Following on from my last thread, which was useful enough that I'm going to push my luck.

 I pulled the negative reviews (1–3 star, with text) for eight Gantt and planning apps on the Marketplace — BigGantt, WBS Gantt-Chart, BigPicture, Structure, Capacity Planner, Easy Agile Roadmaps, Swanly, Gantt Cloud. 284 reviews with actual text in them.

 Sorted by what people complain about, the largest single cluster is speed — 40 of 284. Bigger than bugs, bigger than dependencies, bigger than support.

 The whole category sits at a weighted 4.11, which is the lowest of any functional category I measured across 6,059 Marketplace apps. BigGantt 3.46 over 273 reviews, WBS Gantt-Chart 3.48 over 160, Gantt Cloud 2.96 over 85.

 The review that made me look twice:

  "Waaaaay tooooo slooooow... I only have two projects with about 20 tasks each"

 Twenty tasks isn't a data volume problem. That's a server problem — and several of these complaints do point at the vendor's backend ("their servers were responding...").

 Disclosure: I'm building in this space, so here's the question I actually need answered rather than the one that flatters me:

 1. When your Gantt or timeline app feels slow, is it slow at a size where it obviously shouldn't be? Or is it slow because you're genuinely throwing thousands of items at it?

 2. The one that matters: have you ever actually switched apps because of speed? Or is it an annoyance you complain about in a review and then keep using the thing anyway?

 3. If you did switch — what did you switch for? Speed, or something else that happened to also be faster?


 3. If you did switch — what did you switch for? Speed, or something else that happened to also be faster?

 I ask because complaining and switching are very different behaviours, and 40 reviews mentioning speed tells me about the first one, not the second. If everyone just absorbs it, that changes what's worth building.
