Ragnarok Journey – How to beat Dark Lord Chiyo

Posted by dedieko

My notes for playing Ragnarok Journey :

we have to beat Dark Lord Chiyo, part of Hunter Job Level 83 Quest,

My current Char stat didn’t strong enough to handle him

I have tried playing around with cards.

Increasing Flee Stat by +20 with Nine tail card? Not helping

20% damaged decreased from neutral attack with Rayric card? Not helping

Chiyo is Darkness element , ISIS card didn’t help either

THE POTENT SOLUTION IS : You need to buy LOTS of Large Red Potion

And it’s over within 2 minutes 🙂 hehehehehe

How to Spot & Solving IO Bottleneck problem in Vmware Server 2.x with SSD HDD

Posted by dedieko

In this article, I will try to point my solution for solving IO Bottleneck in Vmware Server 2.x

Firstly, why use virtual solution in the first place? Well there are many subjective reasons, and but for me my main reason is Electrical Consumption. Running multiple guest OS under the same physical Server will greatly reduce electrical consumption. At the moment, our server ( AMD X6 with 8GB RAM) are hosting 10 Guest OS : 3 pfsense, 5 ubuntu server, 1 IPCOP, 1 Windows XP. I can save up to 90 %.

Some of my friend ask me, there is gonna be performance hit by running virtualization. Of course there is, but, in real world application, it’s very rare to see your server running in 100% utilization, since most of the time, it’s doing idle/nothing. Performance hits can be spotted when it start to slow down / under perform, most of it are caused by bottleneck in CPU/Memory/IO or hardware problem.

How to Spot Bottleneck :

If you run vmware server under linux, you can use TOP command to monitor server load. Here is an example:

root@vmserver002:~# top
top – 11:06:56 up 5 days, 8 min, 2 users, load average: 1.42, 1.75, 1.70
Tasks: 244 total, 1 running, 243 sleeping, 0 stopped, 0 zombie
Cpu(s): 2.9%us, 15.7%sy, 0.0%ni, 80.6%id, 0.3%wa, 0.1%hi, 0.4%si, 0.0%st

Mem: 8193488k total, 8118824k used, 74664k free, 38152k buffers
Swap: 0k total, 0k used, 0k free, 6919920k cached

As you can see, I run 10 guest OS, and the CPU load are +- 20% (80% are idle). And this is a production server, not testing server.

Cpu(s): 2.9%us, 15.7%sy, 0.0%ni, 80.6%id, 0.3%wa, 0.1%hi, 0.4%si, 0.0%st

legend:

us : % CPU used for user space application
sy : % CPU used for system space application
ni : % CPU used for application with nice attribute
id : % CPU not used / IDLE
wa : % CPU in waiting due to bottleneck in IO

Pay attention to the "wa" attribute. When I use regular IDE/SATA HDD, the "%wa" is most of the time reach double digit and the total of "%us" + "%sy" is hardly ever reach 10%, that means, my server is under IO bottleneck. Ever since I switch to SSD HDD, which are pretty cheap nowadays, "%wa" is always very low, just around 4-5% at peak load (at system boot or when starting guest OS simultaneously.

So, upgrade your hard drive to SSD. Your system may reside at the old IDE/SATA hard disk, but make sure the storage for guest OS are reside in the SSD HDD. Also consider investing in main board with SATA 3 / SATA 6 port. My main board is still SATA 3, with both the main HDD and SSD HDD are in the same controller, and it’s not a real issue.
