I don't know, I'm quite fond of IRC + automatic picture loading + OAuth Support out of the box + standard client across multiple operating systems + video chat + voice calls + common bot framework + common webhook framework with multiple company's buy-in

edit: to be clear, this is what Slack brings to the table.

> standard client across multiple operating systems

In my case, it's suboptimal. There's a multi-second delay between when I type and when the characters show up on the screen. If I were able to use an OS specific client that didn't have these performance issues, then it would be a far better experience.

I wonder if you've only tried using the web client. I see the same terrible delays in the web client, even on a monster PC where it seems there should be no excuse for slowness.

However, it seems better in their "native" electron client. Still no excuse, performance is terrible in the web client, in my experience, and I'd prefer to use that if I could.

Just filmed myself pressing a key on slack (linux client). Framerate was 30fps.

5 frames / 160ms for the key to appear at the start of a chat line.

3 frames / 100ms for the next key to appear

Firefox in a plain text box takes 2 frames / 65ms

What OS you using? I haven't noticed an issue on the rare occasions I use my (7 year old) mac

I'm using Firefox on Fedora 31, but this seems to be an issue across multiple OS versions. The machine is a Dell Ultrabook with a Core i7 processor and 16 GB of RAM.

filmed at 240fps so 4.17ms per frame. Desktop from 2014. Intel CPU and GPU. 60fps 4k monitor, so 16.67ms per frame.

Slack desktop application best case: 325ms with spell check disabled.

Telegram desktop application worst case: 25ms with spell check enabled

I am sure I wasn't precise in my key press detection. Nonetheless it's still a really sad difference.

It's odd. What desktop environment are you using? Mine's from 2014 or 2015 with xfce. spell check is enabled from the looks of it, but only comes in when I press "space".

Try turning off spell checking. Even then, there is a noticable lag. But better than nothing.
