Please share this configuration:

MINING POOL: bfgminer3.9.0.1 - mcproxy3 - stratum-mining-proxy - mining-pool BFL 30GHS

thanks..

I am trying to use Ubuntu but some how the network speed is real slow. is this normal... the procedure to use p2pool VirtualBox

is your ubuntu instance running in a virtual machine?
how are you measuring network speed?

I use this...

But speed is slow 10-12 with the pool. Should be 30-38.

"C:\Program Files\Java\jre7\bin\java.exe" -d64 -jar "C:\Program Files (x86)\Mediterraneancoin\mcproxy3.jar" -p 8082 -s localhost -a

@echo off
cd \bfgminermed\
mining_proxy.exe -o ibipot.com -p 3333 -gp 8082 -sh ibipot.com -sp 3334 -v
pause

@echo off
cd \bfgminermed\
bfgminer -o http://localhost:8080 -u user -p pass --http-port 8332 -Q 0
pause

configuration look correct.

MediterraneanCoin's PoW is quite different from Bitcoin's Pow (which depends also on CPU power) so the max hashrate you get with ASIC cannot be equal to the max hashrate you get with MED.

Another user has reached 22 GHash (pool side) with a BFL 30 Ghash (how comparable is it to your ASIC?)

the main difference is that he is using his own private php-mpos instance (i.e. he is the only miner and this can influence the pool strategy for diff).

I suggest you setup your own private php-mpos instance and see what changes.

Were to run the proxy and bfgminer after create the ubunto virtual pc, in Ubuntu or in the real pc?

Sorry my mistake is like this

@echo off
cd \bfgminermed\
mining_proxy.exe -sh ibipot.com -sp 3334 -oh localhost -gp 8082
pause

With proxy3 you are going to get a lot rejected share, you can try it mcproxy3.jar and mcproxy.jar.

How was the test???
