How can this happen?
Was that output produced by Valgrind 3.7.0 ? If so, do you get the same
output if you build Valgrind from the SVN trunk ?
Yes it was from 3.7.0. I start a run with SVN
I encounter a problem of running Apache httpd server using Valgrind.
Valgrind seems to decrease the performance of Apache server too much that
the client always report a timeout error. I am also not sure if I used the
correct command line option. I just type Valgrind --tool=xxx ./httpd
Sometimes these crude techniques (not using valgrind) work well enough anyway.
Typically the overhead is a few percent or less.
