Best regards. Yan. Hi, yan We still could see consistent RX performance degression in build-62 on winXP 32 bit guest with default property setting. plese check "Category:TCP_STREAM (RX)" parts in following reuslts: 1. virtio-win-1.4.0 vs build-62 on under default setting http://kvm-perf.englab.nay.redhat.com/results/request/build-62/WinXP.i386.netperf_win.netperf_exe.default_setting.html 2. virtio-win-1.4.0 vs build-62 on under registry setting http://kvm-perf.englab.nay.redhat.com/results/request/build-62/WinXP.i386.netperf_win.netperf_exe.best_registry_setting.html Btw, notice that "OffloadRX.checksum /OffloadTx.checksum" are all disalbed by default in build-62 during our tests. Does it as expected? Based on comment #8 ,re-assign this issue |
hi, Yan Can you help check if the issue is reproductive bug with Bug #826596, if not, will it be modified before submitting the microsoft review? Thanks
