Genesis/AmiTPC slower than MiamiDX. What am i doing wrong?

[AmigaMance]

Hi. Everyone says that Genesis is faster than MiamiDX, both in CPU usage and transfer rates, but i'm not experiencing this and i wonder why!
 My connection is a 2Mbps ADSL one and i'm using a router which is connected to my Amiga 1200 through a PCMCIA network card, driven by cnet16.device.
 In MiamiDX, my download rate reaches the maximum speed, which is about 216 kbps, easily. In Genesis, it tops at about 196 kbps. CPU usage is the same with both stacks. I have tried to tweak the settings of Genesis/AmiTCP many times, without seeing much improvement. Here are the settings that i'm currently using:


AmiTCP.config:

PRIORITY = 1

MBUF_CONF Initial =        2
MBUF_CONF Chunk =         64
MBUF_CONF ClChunk =        4
MBUF_CONF MaxMem =      4096
MBUF_CONF ClusterSize = 1500

;LOG Count =     4
;LOG Len =     128
;LOG Filter =    7
LOG FilterCons = 4
LOG FilterFile = 4

DebugSana = NO
DebugICMP = NO
DebugIP =   NO
Gateway =   NO
IPSendRedirects = YES

TCP_SendSpace = 32768
TCP_RecvSpace = 32768

ConsoleName = "t:AmiTCP.txt"
LogFileName = "t:AmiTCP.log"

 Yeah, i remember that miami performed slightly faster for me, even with a dial-up connection.

@Zac67
That's the TCP_RecvSpace value i have set in MiamiDX too. You are right that 32kb's are enough for my connection. Bigger values doesn't help..

Hello.
 I finally found some time to look at the issue again.
Thank you for all of your suggestions!

@Matt_H
 I have already applied that patch.

@framiga
 There was no improvement with your settings.

@pVC
 Mine is still slower, even with FTP servers.


 Anyway.. I like Miami. The only problem with it, is that it can't handle excessive internet traffic. It corrupts the downloaded data. This happens, for example, when you try to download from a torrent that has many seeders. It is a known bug.
