From: Vijayanand Jitta <redacted> We have tried out the SPF patch series on our code base and have seen significant improvements in app launch latency and ebizzy tests. Please find the results below. App launch latency (in ms) : Apps w/o spf with spf % improvement -------------------------------------------------------- Changba 1531 1252 18.2 Taobao 1813 1506 16.9 QQlive 1966 1775 9.7 Ebizzy test (ebizzy_64 -mRTt 8) : ebizzy_64 -mRTt 8 w/o spf with spf % improvement -------------------------------------------------------------- Avg_records_count 2455 2717 10.7 Avg_real_time 10 10 - Avg_user_time 0.74 0.66 10.8 Avg_sys_time 12.2 11.6 4.9 So, getting this series mainlined would be of great help.
