I'm using Chrome, and the scroll rate is like 3 lines, and it's painfully slow. My finger gets tired really quickly on long pages. System → Preferences → Mouse lacks any scroll wheel configuration options.
This was also annoying me.
This following is one option quoted verbatim from a comment here
Update: I found that the following option actually disabled Ctrl+Scroll to zoom, which I quite like.
I wanted to do this too, and I figure I most often want to do it in a web browser (where else do you really mouse-wheel scroll a great deal?)
For Google Chrome
One can no longer change the scroll amount with command line parameters. However, you can use this add-on extension: https://chrome.google.com/webstore/detail/chromium-wheel-smooth-scr/khpcanbeojalbkpgpmjpdkjnkfcgfkhb?utm_source=plus
There is a new, great extension for mouse's wheel settings in Chrome. Use it and you can customize your wheel behaviour:
Please note unfortunately --scroll-pixels is deprecated and removed from Chrome and Chromium. This flag has not effect on scroll speed.
More details here: https://code.google.com/p/chromium/issues/detail?id=154776
The option to configure mouse wheel speed in chrome seems to have been removed, however the Chromium Wheel Smooth Scroller extension seems to work really well.
The fix for me for this (I had it for months) was pretty surreal and like most folks I didn't believe it until I did it:
Some MS mice have a scrollwheel bug.
Also, I noticed that if you have the dongle plugged in to the computer and the mouse has an on-off mechanism then you can just turn the mouse off and back on. That resets the data link between the mouse and dongle.
In addition there is a Wiki on how to configure input devices that gives you ideas on what is possible at present:
Use xinput to show setting of your input devices:
Only after you know how your mouse is set up you are able to change these setting using
