The same for the 450 univint files:
Peak usage 288M (450 files use 20M on disk):
89M from dl-load
47M from /lib/dl.so which is the lazarus program itself (141M on
disk )
37M from the various grapics initialisation routines loading the QT
libs
2M glib libraries loaded from QT
remainder below ms_print's threshold.
20M KIconLoader (KPixmapCache) triggered by Qstyle::standardIcon from
CONTROLS_TWINCONTROL_$_CREATEWND
107M SYSTEM_SYSOSALLOC <--- fpc
memory management
35M SYSTEM_SYSGETMEM_FIXED
15M SOURCEEDITOR
11M from 167 places below threshold
6M from CLASSES_TCOLLECTION ADD COLLECTIONITEM (from
SOURCEEDITOR_TSOURCEEDITOR)
various smaller blocks in SYNEDIT, EDITOROPTIONS, SYSUTILS,
...
70M SYSTEM_SYSGETMEM_VAR
30M from CODECACHE_TCODECACHE
6M from ZINFLATE_INFLATEINIT called from
GRAPHICS_CREATEBITMAPFROMLAZARUSRESOURCE
17M from LCONVENCODING_ISO_8859_1TOUTF8 from
CODECACHE_TCODECACHE DECODELOADED
3M from IMGLIST_TCUSTOMIMAGELIST
3M from CODECACHE_TCODEBUFFER LOADFROMFILE
1M from GRAPHICS_TCUSTOMICON LOADFROMRESOURCEHANDLE
1M from GRAPHICS_CREATEBITMAPFROMLAZARUSRESOURCE
remainder from several places
17M unknown
25M Qthread (allocatestack in pthread_create)
8M triggered by LCLINTF_SETFOCUS
8M by clone.S
9M by g_main_context_iteration
15M GIMAGE:paintEngine from synedit
2M QFontEngine
2M KMimeType from QFileDialog
8M allocated with brk/sbrk
3M Qimage_paintEngine from LCLINTF_DELETEOBJECT <---- ????
remainder from several places all below ms_print's threshold.
Bad news is that peak memory is reached after closing all files and opening
a new small project (2 files in editor).
