LOL Raid 1 on their backup data server?  WTF?  Raid 1???  Even Raid 5 is no good...   Spend less on equipment, and more on someone that knows what they are doing.

So...  does it seem to anyone that their hardware is extremely underutilized and their software is inefficient?

4x 8 core CPUs and shit tons of RAM should be able to handle more than 1 transaction per second. 

Yes it likely should be sufficient to handle 100x that, assuming the single box was used as dedicated trading engine with other servers used to offload other tasks (API access, webserver, support, charting, etc).

You can't run an exchange as a single-stack application. No way it will scale.

The fact that they are still trying to throw hardware at this means they simply do not understand scaling.

They will not solve these problems because they don't have a clue how to solve them


RUN AWAY, don't just walk away.

The database on the main server should be entirely on SSD.  It's small enough.

RAID1 is appropriate, as disks are cheap, and they really aren't using much space.  Downtime is more expensive than disks.

There should be a secondary server with a copy of the database replicated in real time just for handling read only transactions, like clarkmoody.com, bitcoin itty.org, etc.  And a backup for it, too.  The main server is obviously still overloaded.

They are underconfigured andneed to stop thinking smalltime!  

But most important, they need to stop th spambots from choking the system with .001 BTC orders.  An easy way to do that is set a minimum fee per trade of .006 BTC.  This would only impact the nuisance orders, since any reasonable person is trading at least 1 BTC.

If your systems are behind Nic cards that are 2gbps and you are being hit by a DDos of 10gbps.. how are you supposed to protect from that?  That size DDos will just halt all traffic just from the bottleneck effect.

[MarKusRomanus]

Actually what I meant to say is that their main line into their server room(s) has to be a 1000gbps  capable line.. and they need a minimum of 10gbps bandwidth to survive . their servers behind whatever protection they come up with can be 2gbps  .. no problem.
