Memory usage

Hi, I installed https://aur.archlinux.org/packages/vala-panel-appmenu-xfce-git/ with following options:

_disable_mate=1
_disable_xfce=0
_disable_vala=1
_disable_budgie=1
_disable_unity_gtk_module=0

_opts=(
	-DCMAKE_INSTALL_PREFIX=/usr
	-DCMAKE_INSTALL_LIBDIR=lib
	-DCMAKE_INSTALL_LIBEXECDIR=lib
	-DMAKE_BOLD_APPNAME=ON
)

After couple of hours I noticed that plugin took 2.5GB of memory. Is it expected behavior?
