[Feng Tan]

I have a question about the parallelism. How to judge this?

 

By the way do you have tried to use pump mode for Distcc on Windows?

 

Thanks.

I didn't see anything obviously wrong in the log file.

It doesn't look like a locking problem.

 

Maybe your Makefile doesn't have sufficient parallelism?

 

Or maybe Windows / Cygwin is not switching tasks sufficiently often??

I have figured out why there are always "backoff period" for some machines. 

 

When Distcc ran on Windows, which configured and compiled through Cygwin, the server must have Cygwin installed too.

 

Otherwise there will be no "home" directory on Windows and the Distcc will return fail.

 

But even after fix this issue, Distcc still only connect 4cpus at the same time, also I attached the debug file for your reference.

 

There is no "backoff or warning" now.

 

Thanks for your kindness.

Thanks I'll do more testing this afternoon.

If any update I'll let u know.

 

Thanks again for your help.

That makes some sense, and this is no ADS installed on 192.168.0.232.

 

But I still have a question about the 

 

> Distcc [5364] (dcc_check_backoff) still in backoff period for revo-lufei/4,lzo

 

Why did this happen and how to avoid it?

This happens if distcc has previously, in the last minute or so, attempted to send a compilation to that host and had the request fail.

 

You can temporarily avoid it by doing removing the contents of the "state" and "lock" directories in your distcc directory (~/.distcc, or $DISTCC_DIR),

e.g. via "rm -rf ~/.distcc/state ~/.distcc/lock", before the start of your build.  However, as soon as distcc next sends a request and has the request fail,

it will then mark the host as "bad" for the backoff period (1 minute, IIRC), and will avoid sending new requests to that host during the backoff period.
