Hi,
consider the following statement:
$a = "a" x (100 * 1024 * 1024)
When you create a script which does this over and over again, you'll
observe a strange memory problem.
Can you show your script?
#!/usr/bin/perl
$a = "a" x (100 * 1024 * 1024);
sleep 5;
$b = "b" x (100 * 1024 * 1024);
sleep 5;
$c = "c" x (100 * 1024 * 1024);
sleep 5;
....
perl is made this way. All vars are still in scope and all vars together
require a lot of memory.
How about:
#!/usr/bin/perl
{
my $a = "a" x (100 * 1024 * 1024);
sleep 5;
}
{
my $b = "b" x (100 * 1024 * 1024);
sleep 5;
}
{
my $c = "c" x (100 * 1024 * 1024);
sleep 5;
}
...
Than you get better mmap figures.
