is it better efficiency and performance wise to combine 2 similar plugins into one (assuming no issues with conflict) if they share the same even hooks?

It's modular by design - I've always seen them say keep separate. If your plugins were really that similar why would both be installed to begin with?

Performance wise, if you have 10 plugins iterating through all clients and do something with them on round start for example, then yes, it is faster to combine all plugins. But it will be hell for you to support that kinda of mess.
And, unless you are doing something really dirty and heavy, the effect will be almost negligible.

[ntp]

so in the end, theoretically it is faster, practically negligible. are there any examples of plugins that are really heavy on the server?

[xf117]

WCS probably would be a good example. Each race is a small plugin which not only uses regular Source and Sourcemod events, but also events provided by WCS core itself.
Amount of these races can exceed hundreds.

I have a few servers that exceed about 130 plugins and be it 30 or 130 they will still run just fine. Its best to keep them separated unless you need one to help override the other or control such as overlays and whatever (which I had to do for a few). So if you ask me, keep them separated if you can.
