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. https://technet.microsoft.com/de-de/sysinternals/bb896645.aspx Mit freundlichen Grüßen, Thorsten Schöning -- Thorsten Schöning E-Mail: thorsten.schoen...@am-soft.de AM-SoFT IT-Systeme http://www.AM-SoFT.de/ Telefon...........05151- 9468- 55 Fax...............05151- 9468- 88 Mobil..............0178-8 9468- 04 AM-SoFT GmbH IT-Systeme, Brandenburger Str. 7c, 31789 Hameln AG Hannover HRB 207 694 - Geschäftsführer: Andreas Muchow
