The reason behind this is that we sometimes encounter strange TCP performance issues with out MacOS X 10.5.2 Server (running Kernel 9.2.0) and our clients running MacOS X 10.5.2 (Kernel 9.2.0). Clients which are running Kernel 9.2.2 (it came with the latest "Apple TimeMachine update") don't seem to show the strange problem anymore.

What about clients running 10.5 or 10.5.1?

They were -AFAIK- not affected. It only happened with 10.5.2.

As we spent quite some time with debugging the problem, I would just like to know if (and if so, what) anything has been changed regarding TCP between Darwin 9.2.0 and 9.2.2.

If /only/ 10.5.2 clients are affected, this is probably a Time Machine update change <rdar://problem/5756974>, which backs out a change made in 10.5.2 <rdar://problem/5673601>.

If 10.5 and 10.5.1 clients /are/ experiencing the problem, this might be <rdar://problem/5746798>.

AFAICT these are the only two kernel changes in the Time Machine update. There are other changes that might affect networking (for example, there are changes to the AirPort driver), but they are not kernel changes per se.

All-in-all, it seems like you should recommend that your users install the Time Machine update. Is there a reason /not/ to do that?

No, there is no reason for not doing this. All of our clients are running all of the available updates. But there is no Time Machine update for our server (Mac OS X Server 10.5.2), so the server is still running kernel 9.2.0 and not 9.2.2. We have now just put kernel 9.2.2 from one of our clients on our server which solved the TCP problem also for the server.
