Just keep in mind that these test runs involve perfectly focused, intense play. "real world" play rates are only a fraction of that in my experience. A person wants to feel some sense of advancement in a game like this; for myself I'd say that if I can't level up in a solid day of play, I start to feel like it's static and I'm not accomplishing very much. I hope there is something else coming that would compensate in creating a sense of progress within the game.
You are level 305 in game, this is not a low level and only 11 out of 2,060 players in game have actually reached level 300. This in itself is an accomplishment and something to be proud of. I sure don't have the patience to play to that level nor will I ever lol.
I'll try to explain my position a little better,
TLDR: I understand wanting the convenience of being able to skip pages, but it has a very negative effect on the server.
To begin, as this part will be the main part, MySQL software is very resource intensive, the more stuff it has to display or send the slower it gets and the more the server has to work. As such there is a balance that has to be found that allows the game to run smoothly.
I'm sure you are familiar with the explore page now taking roughly 3 seconds to load, it was anywhere from 8 to 23 seconds before just to move. To fix this I removed a vast portion of the explore map which made a lot of SQL queries. A 3 second load time is still really slow with the suggested highest page load time being 2 seconds though.
Not only did this speed parts of the game up, but it took a lot of stress off the server itself which, in itself, also helps with the rest of the game loading as it freed up server resources.
Now lets say that I were to remove the recent block I added. Players would be able to multi click buttons as you suggest to increase the speed in which they can play and as you said it would help with leveling up faster.
Lets think about what this does exactly for a second.
Player A spams the East button 10 times so they can skip the page loading of the spaces in between. This is very convenient for them for sure, but what they are actually doing is forcing my server to execute 10 large scripts when it was designed to only do 1 script at a time. As you can imagine this would put a much, much larger load onto the server at one time. A larger load on the server means other players will experience delays in their actions slowing their game down as the server usage spikes.
Now lets say 2 people are multi clicking buttons in game for convenience, completely disregarding the other players who are sharing the server as well, this puts an even larger load on the server. Lets not stop at 2 though, imagine 10 players all multi clicking buttons in game or 100, would put a ridiculous amount of stress on the server, which is, again, something the game code wasn't designed for.
Since this was added the servers RAM and CPU usage has dropped drastically as it is now only doing what it was designed to do.
