Topic: Short lags on Server

Hey, i noticed short lags (1-3sec) on my root servers. They only occure like 1 time in 5 hours. Sometimes serveral at once (3 in 30min) and then again none.

By accident i had Teewars double opened and were connected to two different Teeworlds Servers on one root. I noticed that only one of those servers lagged.

So im not sure about HOW this can happen? If i aint got enough CPU power both would lag (same nice setting). If an other process caused this again both would lag because i run TW at low priority (nice -n 2).

Any idea how this could be caused execpt its a bug in teewars_srv?

Re: Short lags on Server

Are you running non-standard maps? It could be caused by people downloading the map from the server before joining. Just a thought...

teeeeeeeeeeeeeeee

Nope all standard. The root is hosting TW only so there is always at least 5 MB/s free...

Re: Short lags on Server

I got the same things, ping goes up almost exactly to 1000ms to all players, then stays there a while, then goes normal again. This affects me also, altough I play on local lan back to back to my server.

Re: Short lags on Server

i dont think that this is a bug.. i have 3 public windows server, 1 windows test server (public) 1 ubuntu test server (not public) .. i havnt that problem .. i run normal, modded servers and all maps are non standart.. but.. i have changed something in source code..
i have changed:
    static const int MAX_EVENTS = 128;
    static const int MAX_DATASIZE = 128*64;
in "gs_common.h" file to:
    static const int MAX_EVENTS = 256;
    static const int MAX_DATASIZE = 256*64;
ping is much better and gameplay also..:):):):)

i have a compiled server.exe .. with this changed things and homing mod .. is also include.. and an extra feture.. the teamhook = instadeath from catpaw thx for this nice thing ...

Re: Short lags on Server

Hmm Dani i think these lags only occure when there are about 5ppl or more. And they occure not very often as i said.

I already blamed "vnstat" for this and postet on his forum until i got a lag 2 days later and hat to revoke my blame :-/

I will try your changes. In fact i got 12 servers on one root but that cant be the problem as only one of two laged i were connected to.

Re: Short lags on Server

i compiled already. 12 is no problem on a root.

but that was not the clue. i think the system lags TW. I changed two of em to niceness -5 by renice trough root and they seem to work fine - for now got to watch some time.
