[Qemu-discuss] Debian 7.8.0 SPARC64 on qemu - anything i can do to speedup the emulation?

[Dennis Luehring]

i've prepared an Debian 7.8.0 image for SPARC64/qemu emulation for C/C++ 
development before-real-hardware big-endian/unaligned tests

using lastest qemu git 2.3.x, with virtio for harddisk and network with 
an qcow2 image

https://depositfiles.com/files/sj20aqwp0 (~280MB
press the "regular download" button, wait some seconds, solve the 
chapca, "download file in regular mode by browser"

there is pugi_sparc.txt in the 7z which describes how to start,use and 
what is installed in the image

qemu runs natively under a ubuntu 15.04 (x64), Core i7, 8GB system doing 
nothing but qemu

installed is

gcc/g++ 4.6
make
sshd running

compiling cmake 2.3.2 tooked around 10h
compiling pugixml takes also very very long

"top perf" from guest and host while compiling pugixml don't show big 
blockers or something over time
