If you do end up getting a ZE server, here are a few things to keep in mind (literally just gonna copy and paste from a post I made in another community, so forgive me if a few things aren't relevant to eGO)
Lag
Obviously there is way to remove lag completely without just getting flat out better hardware, but there are some things that have been proven to be laggy on other servers that may help to change.
1.
Player hitboxes
Many other ze servers only have hitboxes in the feet of their human models so that the server doesn’t have to calculate hit penetration through humans to hit zombies (since the sourcemod plugin, while nice, is inherently laggy). You don't have to worry about zombies being able to knife CTs if you remove the CT hitbox, since the knife's hit detection doesn't use the bullets' hitboxes. If you don’t want to edit the models you already have on the server, you can just steal some from others communities, such as GFL, since all of their CT models have the hitboxes changed. This is also why their default CT model is not the default csgo models, but rather a custom model.
In addition to this, some maps such as ze_space_flight, ze_minecraft_adventure, and a few others change the default model to one included with the map. Typically these map models are unoptimized, and, as such, should be removed. They can be disabled using either just a stripper config, or a stripper config + custom vscript combo. Here is an example of a stripper to remove it on ze_space_flight as a reference:
Stripper:

Vscript for use with the stripper:
https://github.com/gflclan-cs-go-ze/ZE-Configs/blob/master/vscripts/EnforcePlayerModel_patched.nut
The fix would depend on the map in question, so only use the above links as refence on how to fix it, not as an actual fix to everything.
2.
Plugins
Some ze plugins, albeit nice to have, are quiet laggy. It is up to any staff to decide if the usefulness of a plugin outweighs its cpu cost and whether to remove it or not. I have heard that some especially laggy plugins are the player hide plugin, the timer plugin (which checks chat messages for certain keywords such as sec, seconds, etc. and then puts a timer with that message into a game_text entity that counts down), and some anti cheat plugins.
3.
Maps
This is going to be on a map by map basis. There are some large offenders like ze malgo reactor that honestly shouldn’t be on any server due to being terribly optimized, but others just have certain parts that cause lag (such as ze_games, ze_tloz_stone_tower_temple, and a few others). This small laggy section could be something as small as making all the players spawn on a single point during the freeze time before a round starts (since 20+ people stacking on each other is quite laggy on some ze servers), and simply adding more locations for players to be while frozen via the use of a stripper would solve this.
LDR Compiled maps
If a map is compiled in LDR lightning, remove it from the server. LDR compiled maps can, and often do, randomly crash clients either on joining the map or switching off of it. Since this bug was discovered, many maps have been recompiled in HDR to help prevent this. All LDR compiled maps should be either updated or completely removed (if they haven’t been updated). In addition, you should take care to check the compiled settings of any new maps added to make sure they are all HDR compiled. You can either look at map lists of other servers that keep LDR maps off them or use bspinfo (downloaded with bspsrc) on a map by map basis to check compile settings for this.

Fixing Broken Parts of Maps on the Server
If there are bugs in any maps on the server, you don’t need to wait for the mapper to fix them or to compile new versions on your own. If the server has BAILOPAN’s stripper plugin so you can edit the maps yourselves to fix these bugs. While there are limitations on what a stripper can do, as long as you are dealing with entities and not brushes, you should be able to change anything on the map. Hell, even if you want to add brushes to block off skips or exploits, you can use the reuse the model of a trigger and turn it into a func_brush to block it off. Something a stripper can’t fix though, is when a map has badly packed its particles or improperly named them. Maps like these should be straight up removed and the mapper should be told how to fix their particles (More on the particle crashing:
https://rafuron.wordpress.com/2015/...-help-to-prevent-the-infamous-particle-crash/). Strippers aren’t even difficult to make; as long as you know how to map, you can make a stripper config. If you want to learn how to make a stripper, here is the documentation for the plugin:
http://bailopan.net/stripper/
However, even if you don’t want to make strippers, many other communities have some of their strippers publicly available. Just use theirs if you don’t have the fix for a certain map (just be careful because some strippers might add or change entities based on a file/model the server itself has in the fastdl, so in these cases you would either have to edit that or add the file to your own fastdl). In addition to these, certain maps have official strippers out that were published by the mappers to fix some bugs, such as santassination.

Some of Steam Gamers’s strippers (these aren't bug fixes, instead are mechanic additions that change a map's intended design. Hence, not all are good):

In addition to all this, for a new server, like eGO if you made a ze server, focus on adding easier maps first. There is a strong tryhard community in the ze scene, and as such, some maps are incredibly difficult. An example is santassination, which is still not being fully beaten after nearly 3 years since its release (this is even with servers doing up to 8 hour events on just the 1 map). These maps aren't great for introducing new players to the game mode or playing with less than around 40 people in the server due to their steep learning curve and either being multi-level maps or having 30+ minute rounds to beat. Also, some
essential plugins to the server are
entwatch (a plugin that keeps track of in map items that are tied to pistols that players can pick up), BAILOPAN's
stripper plugin, and some form of
team bullet penetration (due to tight holds on many maps, you will lose without this. If you choose to fix this with a plugin, it will be quite laggy in some situations, so modifying hitboxes like earlier mentioned would be better).
