Server Increase performance question.

[qwerty13]

DB engine - memory, and real time replication on different server. Hard drive will be used only for backups.

I installed MySQL and mysqltunner works just fine now
Thanks for advices all.

If you run a pvp server use geodata only in importand areas (castles,farming etc.) I was handling 500 players on 2gb ram with autorestart once everyday.

Ok, I got my new ram, 8GB DDR2 1066mhz.

I have arround 140 players and some of them have lag, still don't know what the problem is, any ideeas ?
Thanks.

how about internet connection ? what bandwidth do you have ?

how about internet connection ? what bandwidth do you have ?

Your RO , I have from iLink, its stable, and fast ... but from what i've noticed only place where its a bit slow ... is greece. ( In greece internet sux, been there )


now the test was good sometimes upload to greece is like 900kb/s

And mostly the ones lagging are from greece ...

[dark911_ro]

with 2 - 3Mbps you can have arround 150 players on your server . Ofc player connection is important also .

But if you say that sometime ur connection goes to 900kbps is bad .. try to get a guaranteed bandwidth starting from 3Mbps.

If you are from Romania , try getting fiber from UPC with guaranteed bandwidth of 10Mbps it's arround 60 Eu / month. Or try RDS but they have a bit higher prices.

Me for ex i have atm both connections ( RDS and UPC ) and UPC is far way better on external , RDS with up min of 50 Mbps and up to 100 Mbps owns intenal . But as you know ... your location is a huge factor for a good internet connection.

As you know , Romania is on 4th place in world for internet connection speed after Koreea, Japan and Latvia So you have where to choose from

Download speed its high for both (RDS and UPC) but upload sucks.. if you want more upload ...well costs are very high

Download Speed: 59830 kbps (7478.8 KB/sec transfer rate)
Upload Speed: 507 kbps (63.4 KB/sec transfer rate)
Latency: 5 ms

my l2server from 1jan until 28jan
Incoming data in gib 206.68
Outbond data in gib 723.34

So how to handle this traffic with 507kbps upload ? You cant

I found the perfect way and cost effective, iLink + NextGen on Fiber (total price 20E/ month).
iLink works for every country perfect except greece.
Hope next week if I upgrade, the lag issues will go away

I am pretty sure l2j server in anyway you want did not and wont make 723.34 GB in 28 days
Maybe you included there your downloads also ...

Maybe he has webserver on same box as server, and ppl download patch/client lol + torrents )

That's an average of around 300 kB/s upload. If you have somewhat of a population you easily use up such amount of bandwidth in just 28 days.

RAID0 of SSD disks.

Just dont do that. Because Trim is not supported by SSD in RAid. That means that theSSDs will became slower with time. The best to do is just buy an SSD and leave it alone. the SandForce ones allready do 285 read 275 write 250 Sustained write. If you buy a REvo Drive from OCZ ( that are in RAID 0, but are prepared for that) you will have 740MBs read 690 Write and 550 Sustained Write. And if that is not enought, you can allways get the new Z-Drive R3 (entreprise Solution) that does an amazing speed of 1GB/s Read 970MB/s Write 900MB/s Sustained write, with everything, like trim, etc etc, and allows you to add more storade if you need more.

I just telling what the crazy people at the Overclock foruns talk about. And they test like 4 SSD in Raid etc, and most of them say the same. Anyway an SSD have allready enought speed. The great improvent for a server will be for sure the seek time of 0.1ms

@Ralm - that's some very useful info, thanks
