Description:

This plugin is a library that allows you to create special infected bot by SIPool.

The plugin's aim is that when your server needs to create special infected bots very frequency.
Such as create 28 SI bots in 0 seconds, CreateFakeClient() will consume lots of cpu and network resources.
But use SIPool can avoid lots of CreateFakeClient() operation because the plugin use pool to manage the SI bots that already created in the past and avoid them being kicked by the director.
When you try to request the bot, SIPool will pick an available bot from pool unless the pool is empty.

And after my test(28 SI with 0 seconds), the result showed that:
NO SIPool, the server's tickrate decrease from 100 to 80 LESS when CreateFakeClient() from a for() loop;
WITH SIPool, the server's tickrate decrease from 100 to 90 MORE when RequestSIBot() from a for() loop;

And the plugin still needs to test, only myself can not make the plugin be pefect, so any advice and criticize reports are wanted.

Q: How does SIPool work?

SIPool will prevent the engine from kicking dead SI(Special Infected) bots and keep them death until next spawn,
for example, a charger bot dead, SIPool will change it's status to ACTIVE to avoid it being kicked,
and add it to charger pool, next time you RequestSIBot for a charger,
SIPool will pick an available client from charger pool and make it respawn,
teleport to target position, then return it's index to the plugin which calls RequestSIBot.

Q: Why can SIPool enhance the performance?

I think the main reason is that SIPool avoid lots of CreateFakeClient operation.
SIPool makes the SI bot to be a player in coop mode, just like versus, dead SI won't be kicked but wait for respawn,
so no new client connect and boardcast to everyone in server, these will save lots of cpu and network resources.

Usage:

See si_pool.inc and sptest.sp.

Wow, will this plugins conpatible with Infected bot harry fork? Because i'm currently running a 16 slots coop server and it spawn a lot of SI at the same time therefore my server tickrate is really unstable.

Unfortunately, currently none of the plugin is conpatible with SIPool because all the old plugins need to rewrite with SIPool in order to get the function work.

I have made a SIPool fork for harry's L4D Infected Bot and I have put it here.
For current only support L4D2 because SIPool only support L4D2 now.

Only test at my server(30 SI 0 seconds with single survivor), the test result is that:
At the moment SI spawn, 95 more tickrate the server has at round start.
With the round continue, lots of SI got lagged and killed by plugin, 85 more tickrate the server keeps.
For the average performance, the server should keep 90 tickrate if SIPool works as expect.

SIPool need to redownload because I have updated it.

After using two versions, the error still appears. Please ask the author to fix it. Thanks.

用了两个版本还是显示错误，还请作者修复，谢谢。
