I just clear other pointer from tcache and fastbin(without small,large). 1. bench-malloc-simple-[8-64] looks like better performance than before. 2. bench-malloc-simple-[128-4096] and bench-malloc-thread-xx are almost the same. Attachment is the results of two rounds testing of bench-malloc-simple and bench-malloc-thread. --=20 You are receiving this mail because: You are on the CC list for the bug.=
