Re: CreateProcess vs Create Thread

CreateProcess has to come first since all the work that happens for the
multithreaded version also has to happen for the CreateProcess version, and
it's just natural that it will come first.

It makes a lot of sense for Postgres to get the CreateProcess version
working and stable before embarking on threads - Win32 and threading are two
separate and mostly unrelated tasks, but threading on Win32 can't happen
until Win32 is stable.

Just my two cents...

Subject: [pgsql-hackers-win32] CreateProcess vs Create Thread

Hello,

   O.k. there has been a lot of discussion in regards to what the best
method to take with PostgreSQL Win32 is.
It seems that the community is set on using CreateProcess. If this is the
case I have a couple of further questions:

1. Are we just a bunch of Unix coders trying to develop a product for
Win32 or are there any people a part
of the Win32 port project that actually have REAL, hardcore experience
coding at the system level for Win32?
I am not trying to be an antagonist but I it is a legitamate question.

2. Have we built a test case? For example:

    We have a client that connects to a server. For every connection we
start a new process and write 1k to disk from the client.

    Connect in varying degrees from 5 connection to say 500 connections.

    Do it with CreateProcess and the with CreateThread... Time the
difference, and review the load on the server during the tests...

    What is the difference? Maybe it is nominal enough not to worry about
it... Maybe it's not.

Sincerely,

Joshua D. Drake
