comunication protocol

Hi,
I have installed postgresql to my client as a server for a progam (libpq.dll/VCL based) that I wrote for them.

Every is working fine, but I noted some general slowness, compared with an older database system (iAnywhere ADS)
due (I think) to the text based communication protocol.

I know there is the possibility to adopt a ssl compressed connection but I think a pure compressed connections could be better.

So, I have studied the postgresql sources and I have tried to implement some compression between the backend and the frontend,
using pglz_compress/pglz_decompress on be-secure.c and fe-secure.c.

At the moment is working good on a local configuration, got some problems on a remote connection due I think a different way to communicate.

There are other ways (other than be-secure and fe-secure) with which the backend comunicate with the frontend?
And, do you think this solution could speed up something?

For the moment I have big troubles to debug the server, have you some informations how to debug it with MinGW?

Thanks and sorry form my english!
