I will look into the IBPump and see if the dll is compatible with VB6. If
it is, I will give it a shot.

Subject: [firebird-support] Re: At my wits end
I'll throw in my two cents worth. One of the applications I write
involves daily imports. I use IBpump by Clever Components. I use
the DLL and compile it into my application. I don't know by, but
IBpump is much faster than any other tools I've tried. I get about
1200 inserts per second, and I'm inserting about 40 fields, and
about 800 bytes per record. This is over a 100MB connection.
I have played with another solution that is even faster, but have
not implemented it yet. Are you able to create store procedures on
your server? If so, you could insert the entire file into a blob
field in a "staging" table on the server. This is not much slower
than just copying a file from a client computer to the server. It
would probably take a few seconds in your case. Then you could
write a stored procedure to parse this blob field, and insert the
records into the destination table(s). In my test, I net about 5000
inserts per second, but the stored procedure has gotten a little
complicated.
