Open Excel file very long with wfsave

Postby Bob » Sat Jan 22, 2022 2:41 am

Hello

My Eviews program imports data from a closed Excel file ("import" command) then performs sequential calculations under Eviews and exports the results to another open Excel file ("wfsave" command).

The execution time is long (5 hours and 30 minutes) given the volume of informationprocessed.

However, a few times, the program was fully executed in less than 20 minutes!

I noticed that it was when running wfsave that the processing time could change (the mention "open Excel file" at the bottom left of the Eviews screen remaining displayed more than 5 seconds in case the program goes slowly and is almost instantaneous otherwise).

Note: the computer has just been remastered (everything is clean) there is for the moment only Windows defender.

Do you have an idea?

A big thank you in advance to the whole team :)

Bob

How many times are you doing wfsave?

2200 wfsave (principalement des séries chronologiques annuelles 1980-2021)

remarques :

Avec Excel uniquement, mon fichier de 30 Mo s'ouvre en 8 secondes environ.

Avec Eviews, l'écriture dans Excel avec wfsave utilise presque 5 heures (2200x8s) puis il y a aussi l'importation de données et leur traitement.

C'est comme si à chaque écriture (utilisation de wfsave) Eviews ouvrait mon gros fichier Excel alors qu'il est déjà ouvert.

Ce qui est étonnant, c'est qu'il est arrivé que le programme Eviews tourne en mois de 20mn !!! d'où ma frustration :)

Bonne journée

The first time you save to the file in the program, use the option

Code: Select all

wfsave(mode=update_hold)

instead of mode=update (which is what I presume you are using currently).

Just the first time, after that you can use mode=update.

Then the last time use mode=update_release.

Bonjour,

Merci pour l'idée mais mon programme ne fonctionne pas plus rapidement !

voilà comment j'ai traduit votre message :

1er wfsave :
wfsave(type=excelxml, mode=update_hold, noid) {chemin_fichier_mod} range="MDE!h7" byrow @keep pibvolp_mde_fmi @smpl @first {date_fin_obs}

2ème wfsave et suivants :
wfsave(type=excelxml, mode=update,noid) {chemin_fichier_mod} range="MDE!h14" byrow @keep pibdeflp_mde_fmi @smpl @all
...

Dernier wfsave :
wfsave(type=excelxml, mode=update_release,noid) {chemin_fichier_mod} range="MDE!h78" byrow @keep mscipr_mde_eur_vol1a @smpl @all

Bonjour,

Voici le code de mes derniers tests

wfcreate(wf=test2,page=AN) A 1980 2025
string chemin_fichier_mod = "C:\AMF\Analyse-Macro-Financiere-mod.xlsm" ' fichier de 27,4 Mo
string chemin_fichier_data = "C:\AMF\Analyse-Macro-Financiere-data.xlsx" ' fichier de 28,6 Mo
string m
m="2025"

tic
import(page=an) {chemin_fichier_data} range=a_MDE!$E$17:$E$71 colhead=8 namepos=first na="#N/A" @freq A 1980 @smpl @first {m}
scalar temps_read=@toc ' entre 1s à 5 secondes, selon les essais, pour lire 1 série chronologique annuelle sur 1980-2026 (fichier excel fermé --> decompression et lecture ; à noter : c'est plus long avec le fichier excel ouvert !)
toc

tic
pageselect AN
'wfsave(type=excelxml, mode=update_host, noid) {chemin_fichier_mod} range="MDE!h8" byrow @keep pibvolp_mde_fmi @smpl @all (test solution EViews Gareth)
wfsave(type=excelxml, mode=update, noid) {chemin_fichier_mod} range="MDE!h8" byrow @keep pibvolp_mde_fmi @smpl @all
'wfsave(type=excelxml, mode=update_release, noid) {chemin_fichier_mod} range="MDE!h8" byrow @keep pibvolp_mde_fmi @smpl @all (test solution EViews Gareth)
!elapsed = @toc
scalar temps_write=@toc ' entre 11 et 13 secondes selon les essais (ou exceptionellement 0,5 seconde !) pour écrire 1 série chronologique sur 1980-2026 (fichier excel ouvert --> openning excel file, scanning for data...)
toc

' Remarques :
' wfsave a mis 0,5 seconde que quelques fois après un "nettoyage de disque windows" mais aussi après avoir décoché "compile to intel machine code" sans que cela soit reproductible !!!
' Il me semble qu'il y ait un problème de cache ???

I'm afraid we don't have much alternative right now. The next version of EViews, EViews 13 will have a faster Excel writing engine (that doesn't use Excel!).
