3h, 50m later..



is this normal in SA-MP?

(CPU, memory usage..)

Plugins:
- Object Streamer
- MySQL
- sscanf
- crashdetect

CPU goes up, not down.

I would expect this as with MySQL.With values being both read and written into a database, the memory usage should increase significantly!

yes, thats normal. each player takes some memory to get processed by the server. from the CPU values i see, you can expect the CPU usage rising up 10% more with 125 players:
87 players: 5.3% cpu
105 players: 9% cpu (almost double the CPU-time for just 18 more players)
125 players: 20% cpu time predicted.

players, interacting with others, are using CPU time. if you take 80 players, then each single player will use functions which calculates 79 times for all remaining players.
80*80=6400 script "cycles" (or callbacks/functions, whatever runs in your script - it uses CPU). compare that with the amount caused by 20 more players:
100*100=10000. that, compared to 6400, is almost 2* the amount of cycles needed. now again 20 more:
120*120=14400. more than double CPU time needed, for half more (80+40) players...

as you see, the RAM usage goes up linear, but the CPU usage raises logarithmic.
lets match that "formula" to your CPU usage:

Код:

085 players =   7225 interactions,   5% CPU,
105 players =  11025 interactions,   9% CPU,
125 players =  15625 interactions,  13% CPU,
now extreme:
200 players =  40000 interactions,  35% CPU,
300 players =  90000 interactions,  80% CPU,
400 players = 160000 interactions, 150% CPU,
500 players = 250000 interactions, 250% CPU (most prolly more)

i hope you got what i mean, it needs a beast of a PC to host a lagfree server, running a complex script, for large amounts of players...

thanks for answer
but is this normal that the CPU goes not down?

8:00 PM - 120 players, ~20% CPU
next day at 6:00 AM - 10 players, ~23% CPU

close the server to cpu go down :P
jking

well.... if u have more players or if it is turned on lots of time yes

yes :P
server auto restart 6:00am

but no other way? :>

buy an host....
home host isnt good.....

it's a root
the pic show's the root perfomance.

not bad o.O
my pc is 1/4 of that :P

Hey,

SA:MP is Singlecore, i think.
How other Server reach 800 Players, with <100% CPU?
