Win 7 support
Hi All,
We are using log4cxx 0.10 and experience major slowdown of our system running on win 7 32 bit OS (6 times slower !).
We use only rolling file appender for writing logs.
Does anyone experienced something similar ?
Appreciate any input on this topic.
Best Regards,

And same HW means you really installed Win7 bare metal and not a VM on the
XP host? Because in that case it's obviously not the same hardware. As
Win7 is on the market for years now and I don't experience any
performance problems with Win7 nor Win8.x using a slightly patched
0.10.0 myself, I don't believe there's a fundamental issue in log4cxx.
Additionally, most of the OS dependent things are implemented by APR
and not log4cxx.
As you already know that your software is 6 times slower now, what
exactly is the bottleneck? Did I/O load or latency increase or that of
the CPU, does rolling files take more time now, which strategy do you
use for rolling files... Does the problem occur with other appenders,
which don't use rolling file appender, but only log into one and the
same file? I'm able to log hundreds of MB with TRACE level that way.
If you don't know the bottleneck yet, find it using resource monitor
of Win7 to monitor load and I/O latency and Process Monitor to see
which file operations are executed by your application and how long
they take and such.

Slower compared to what under which circumstances before? Another OS, other hardware, another version of log4cxx, other configured loggers or log level or...
You really need to provide more details, else I guess that you simply need to close the tab in your browser which is still consuming porn for the last 24 hours and caching GBs of streaming video data to your local hard disc, which of course is the bottleneck in your tested system... ;-)
