[Gluster-devel] Why integrate both client and server into a single executable?

[Kirby Zhou]

I use RHEL-5.2
What's your point of the distribution? 'NO_CONTENT_TYPE' problem or FUSE problem?
The FUSE rpm does not come with RHEL, it should come from somewhere I do not know now.

Do you mean you can set up both client and server in the same process? How can I do it? Is it a new feature in the 2.0rc1?

However I do not think it is always a good idea, the server role is much more stable than the client role. If you mix the 2, you would lost the stability.

If it's a server-only (or client-only) setup, then there's only one process
anyway, so I don't see a problem. If a machine is both a client and a
server, then having both in a single process results in a considerable
speed-up because it avoids a process switch and doesn't have to push all of
the communications through the socket layer and/or the IP stack. The
performance boost (and the CPU usage drop) is quite noticeable on my
systems.

What distribution are you talking about? I don't remember this being the
case on RedHat based distributions.
