After my previous thread, I think I found out what causes the long delays.
I run this program on several Linux computers, and the sometimes (after the file with the arrays becomes big) the fwrite takes between 100 ms to 900 ms.

LINUX(4) BSD Kernel Interfaces Manual LINUX(4)
NAME
linux -- Linux ABI support
SYNOPSIS
To compile support for this ABI into an i386 kernel place the following line in your kernel configuration file:
options COMPAT_LINUX
for an amd64 kernel use:
options COMPAT_LINUX32
Alternatively, to load the ABI as a module at boot time, place the following line in loader.conf(5):
linux_load="YES"
DESCRIPTION
The linux module provides limited Linux ABI (application binary interface) compatibility for userland applications. The module provides the
following significant facilities:
o An image activator for correctly branded elf(5) executable images
o Special signal handling for activated images
o Linux to native system call translation
It is important to note that the Linux ABI support it not provided through an emulator. Rather, a true (albeit limited) ABI implementation
is provided.
The following sysctl(8) tunable variables are available:
compat.linux.osname Linux kernel operating system name.
compat.linux.osrelease Linux kernel operating system release. Changing this to something else is discouraged on non-development systems,
because it may change the way Linux programs work. Recent versions of GNU libc are known to use different syscalls
depending on the value of this sysctl.
compat.linux.oss_version Linux Open Sound System version.
The linux module can be linked into the kernel statically with the COMPAT_LINUX kernel configuration option or loaded as required. The fol-
lowing command will load the module if it is neither linked into the kernel nor already loaded as a module:
if ! kldstat -v | grep -E 'linux(aout|elf)' > /dev/null; then
kldload linux > /dev/null 2>&1
fi
Note that dynamically linked Linux executables will require a suitable environment in /compat/linux. Specifically, the Linux run-time
linker's hints files should be correctly initialized. For this reason, it is common to execute the following commands to prepare the system
to correctly run Linux executables:
if [ -x /compat/linux/sbin/ldconfig ]; then
/compat/linux/sbin/ldconfig -r /compat/linux
fi
For information on loading the linux kernel loadable module automatically on system startup, see rc.conf(5). This information applies
regardless of whether the linux module is statically linked into the kernel or loaded as a module.
FILES
/compat/linux minimal Linux run-time environment
/compat/linux/proc limited Linux process file system
/compat/linux/sys limited Linux system file system

HISTORY
Linux ABI support first appeared in FreeBSD 2.1.
