Dedicated Server System Bug

Postby mars888f » Thu 6 Mar 2014 03:39

Hi Eugen team Sir:
i found a very serious bug in your dedicated server system.
it add more 20% CPU usage in WAB lobby or any dedicated server room.(CPU usage 35~40%)
Ref attached B3 & B1 photo
client host room lobby is normal(1v1~4v4host. CPU usage 10~15%)
Ref attached B2 photo
Test Computer: only Client-PC
Intel i5 4670k 3.8GMHz 4Core, 8 G DDR3 ram 2400Mhz, Win7 64 bit OS ,GPU:R9 270X hawk, H/D 7200rpm
These additional CPU' consumption will be added to the ingame.
additional 20% will not be released ingame.

Benchmark:
experiment condition: same map, same 1V1 or 4v4
*host room CPU' usage:10~15%
*dedicated server room: CPU' usage 35~40% (same map and 1v1 or 4v4 ;
more add 20% CPU usage )

Another PC test is same result.(Intel X5460,8G ram 1333MHz,GPU:GTX650,Vista 64bits OS)
it add more 20% CPU usage in WAB lobby or any dedicated server room.(CPU usage 45~50%)
client host room lobby is normal(1v1~4v4host. CPU usage 24~28%)

Intel X5460 PC often be kicked out in the middle of 10v10 ingame(new Gjöll map).
because by "your computer performance is too slow than other players" .
So i buy a new PC i5 4670K. it not kicked out in the middle of 10v10 ingame.(Gjöll map).
i think why most players often see "your computer performance is too slow than other players" in the middle of 10v10 ingame.
if reducing 20% CPU consumption, X5460 will be not kicked out in the middle of 10v10 ingame.(Gjöll map)
CPU usage is big issue for data processing lag.
More units fighting ,more data processing. :lol:

uhm...

i may be totally wrong...

but:

- you should test in full-screen mode, to avoid bizarre distortion of results.
i did a quick test (by far not in that detail, that you did, but i seem NOT to have any critical differences between "in lobby", "in 4v4 lobby" or ""in 10v10 lobby")

- you should also not look at or report screenshots of single results, but some performance graphs, which show result-tendencies over some timeperiod
f.e.: a chart, that directly shows a "leap", when switching from lobby to a 10v10 match or somethings alike.

single screenshots of single results don´t tell the full story.
;)

so, better have a charting tool running (possibly a large chart, all over your screen, to be nicely and detailed in your screenshots), start the game, do your check-condition (like "entering a 10v10 lobby now") ,stay there some few seconds, ALT-TAB back to your chart tool, make screenshot.

now, you should see f.e. the cpu load "before" and "after" and if that load was for some time or just a spike.

i got curious...

i did some more tests:

i run the game-client and a server via VM on the same machine.
i have an i5/750 @ 2,76 GHz, 4 GB RAM, nVidia geforce gtx 275
so, absolutely no "high end" rig at all...

i can play up to 10v10 without any real problems, most times.
if i do, i do it on my server, rarely on the official 10v10´s

if i start the game, i get about 20-30% systemload on all 4 cores, in the gamelobby maybe 5% more, in a game´s lobby basically the same

i started my server, too and went into it´s lobby, to have the best possible net connection (2ms is ok for me here)
:twisted:

then i started a game with lots of cash, me vs nobody...
i purchases tons of units, masses of cheap stuff, to simulate a bidder match.

all was moving smoothly, systemload was between 50-80% (=including the running server)...
then ... boom ... i suddenly was kicked from my server!?!?

that never happened to me before!
server console just tells "connection lost"... nothing really more...
also no "kicked due to bad performance"

that´s this test-match...
looks pretty normal to me.
Image

after that, being in the lobby to see the match-after-report, my GPU load goes up to 90-100%!
fan is also running in full-speed.

leaving this after-match-report, back to normal game lobby, GPU falls down to normal load immediately..

what´s going on there?
voodoo magic!?!?
:twisted: :o :twisted: :shock: :twisted:

attached photo is allowed for 250k bytes in this forum.
i just inform Eugen team of strange CPU consumption.
*(Benchmark: host room VS dedicated server room)
if he think it not a bug. forget it.

Benchmark:
experiment condition: same map, same 1V1 or 4v4
WAB game window: 1680*1050 ; my monitor: 1920*1080 ; Com: i5 4670K
*host room CPU' usage:10~15%
*dedicated server room: CPU' usage 35~40% (same map and 1v1 or 4v4 ;
more add 20% CPU usage. additional 20% will not be released ingame. )
photo cc4 is WAB lobby ( 60 sec chart ,CPU usage VS time )
photo cc5 is WAB lobby come into 10v10 dedicated server room
photo cc4 is WAB lobby come into 4v4 host room

i have a 2500k @ 4.5ghz and 8gb of ram

in the menu screen, wargame2.exe CPU usage is at 25%, distributed evenly across all 4 cores
in a 10vs10 lobby, usage goes up to 35%
in-game, usage peaks at 70%

it's a slight bump, but i'm not sure if this should be considered a bug. besides, what harm does that extra ~10% of usage have?



note if you really want to stress your CPU, i'd recommend playing on WGG #9, which has unlimited deployment points...

i think extra 10% is a bug.
i find a way to reduce 10%(20% for me) in 10v10 room. :lol:
by the way! i often attend WGG server gaming.
WGG#9 is a good place to testing CPU' stress.
Where's WGG server located in ? USA?
Here's my dedicated server "[Mars] ASIA SERVER".
but not always turn on everyday.

so, you are having in the ALB lobby-menue and in a 10v10 lobby about 35% average, in a 4v4 lobby 15%.

don´t get me wrong, but: so what?

much more critical for you will be, that your cpu seems NOT to distribute the system load between all 4 kernels.
you have 1 pretty high load on one kernel, 3 much lower loads on the others.
your system is not loadbalancing betweed the different kernels properly.

naizarak and me seem to have pretty good balanced load between all available cores.
this is by fare more important than some more or less percent in one or the other lobby.
we both have intel CPUs. i don´t know, if your non-even load-spread is due to AMD habits (= "is this normal for AMD CPUs?) or if the game mayve doesn´t loadbalance properly on your CPU-type...

finally: why do you care that much about systemload in the lobbies?
for sure, it´s an interesting topic...
but maybe more of an "academic" kind.
you should maybe better racord your systemload during running matches, to find out, if your disconnects have some measurable relation to too-high systemload during bifg matches.

so why don´t you share this secret?

So a 4v4 lobby uses less resources than a 20 player lobby? Is that what you are getting at? As Naiz says, "So what?" It's a larger map in 20 player, why wouldn't it be grinding more textures, etc?

my CPU are Intel (Q9300,X5460,i5 4670K). not AMD
i will share the secret after Eugen' response.
First,i'm waiting for Eugen' response for this benchmark issue.
the reason why ? is it not a bug?
experiment condition: same map, same 1V1 or 4v4, Com:4670K
*host room CPU' usage:10~15% (choice same map and 1v1 or 4v4 )
*dedicated server roomCPU' usage: 35~40% (choice same map and 1v1 or 4v4, not 10v10 ;
more add 20% CPU usage )

finally: why do you care that much about systemload in the lobbies? ==>
if systemload 35% in lobby, CPU 35% start after entering game. 20% accumulate ingame !!
if systemload 15% in lobby, CPU 15% start after entering game.==>better than 35% in lobby !!
if Q9300 55% reduce to 35% ingame,it's not a good thing for you &me & all player?
i very love the game. i often play. i buy 2 sets of WEE and WAB.
because my first PC Intel Q9300 often be kicked out in 10V10 Gjöll map everytime(after 20~30min ingame).
Q9300 in WAB menu or 10V10 lobby has 55% CPU usage(X5460 45% , 4670K 35% CPU usage)
So i check my CPU & GPU & RAM' usage ingame. which key part is not enough for been kicked out the game.
i found that CPU 95%~99% , GPU 50~70% , RAM 35%(8G RAM), ping 280~320ms(Taiwan to France)when kicked out. and screen show "due to your computer performance is slow than others players XXXXsec.
it's obviously that CPU shortage ingame.
So i buy 4670k and X5460 CPU for CPU shortage ingame. then i sold Q9300 CPU.
4670k is all new PC hardware. ==> run all 10V10 is good. never been kicked out ingame.
X5460 only exchang CPU from Q9300. ==> run Gjöll map not be kicked out everytime.
it seems better than Q9300 ingame.

pls watch my benchmark first!
