> http://pastebin.com/n60pN1LL The line SYSCALL[11763,1]( 0) sys_read ( 4, 0x90b2e34, 38346752 ) appears many many times. A read() of 38MB is done over and over and over again. That's expensive. A read()-from-a-device is a write-to-memory, so memcheck must mark those 38MB as valid, over and over and over again. -- |
