Hi,
Try turning off your Anti-Virus protection on your desktop. Maybe you will
notice better performance.
You can increase the "Local Data" cache of your SAP Gui too. You never
know.
Try on different desktop configuration (Win XP vs Win 7, 4Go Ram vs 2 Go
Ram etc., CPU speed). You will have a better idea where your is
bottleneck.
Regards,
Pierre

Subject: Speed of Download to Desktop VS App Server
Hi all,
I suppose that this is due to network latency, but I thought I'd ask anyway.
My code does exactly the same things until download time. Then it forks either taking the data off to the APP Server or to the desktop. I was pretty surprised when the speed ratio came out 100:1 in favor of the App server. Is that really a reasonable expectation? Here's the two code bits:
For the local download:
FORM file_ldownload.
DATA: l_file TYPE string.
* Download file to presentation.
MOVE: p_lfile TO l_file.
CALL METHOD cl_gui_frontend_services=>gui_download
EXPORTING
* bin_filesize = l_xml_size
filename = l_file
filetype = 'ASC'
trunc_trailing_blanks = ' '
CHANGING
data_tab = it_output
EXCEPTIONS
OTHERS = 24.
IF sy-subrc EQ 0.
WRITE: / 'Files written to the local drive:',
/ p_lfile.
SKIP 1.
ELSE.
MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
ENDIF.
ENDFORM. " FILE_LDOWNLOAD
For the App Server download:
FORM file_sdownload.
DATA: l_error TYPE string.
* file download.
OPEN DATASET p_sfile FOR APPENDING IN TEXT MODE
ENCODING DEFAULT WITH WINDOWS LINEFEED
MESSAGE l_error.
IF sy-subrc NE 0.
IF sy-subrc = 8.
MESSAGE l_error TYPE 'E'.
ELSE.
MESSAGE ID '/SAPDMC/LSMW' TYPE 'E' NUMBER '056'.
ENDIF.
ELSE.
LOOP AT it_output INTO wa_output.
TRANSFER wa_output TO p_sfile.
ENDLOOP.
CLOSE DATASET p_sfile.
IF sy-subrc IS INITIAL.
WRITE: / 'Files written to the server:',
/ p_sfile.
SKIP 1.
ENDIF.
ENDIF.
ENDFORM. " FILE_SDOWNLOAD
Any thoughts on this?
