Marc, It looks like you need to understand how RBase syntax analyzer and the Rbase optimizer is interpreting and processing your view statements. Try issuing the following commands SET DEBUG ON SET VAR MICRORIM_EXPLAIN = 47 RETURN *(MICRORIM_EXPLAIN This variable shows the decision the optimizer made when executing a particular command. The optimizer results are placed in the file EXPLAIN.DAT. The DEBUG command must be on to use microrim_ explain.
The available options for microrim_ explain are 1 - output the table order. 2 - force optimization of joins over five tables. This option is ignored if microrim_fullopt is set. 4 - output the command file name and next byte offset. 8 - output the current date and time. 32 - display the sort technique used. To use multiple options, add the option numbers together and set the variable to the result. For example: SET VAR microrim_explain = (1 + 4 + 8) SET VAR microrim_explain = 13 ) Then run your report. Look at the Explain.dat file. You may need to do this in both versions to see if RBase is interpreting the views differently between versions.

Marc It sounds like you should do the PROJECT TEMP ... command from your view (include the WHERE clause in your PROJECT), base the report on the temp table instead of the view.

PRINT NewForm76D WHERE tr_date BETWEEN 1/1/09 AND .#date AND insco1 = 7 AND compnum = insco1 ORDER BY insco1, custnum, tr_date The report is based on a 6 tab view, Browse all from View using the same where clause only takes 1/4 the time compared to the Print statement. Leaving off the Order by does not make any difference. I am using a copy of the same DB converted to V8, so all data, reports and indexes are the same. I did notice that the #1 file was 46 k now it is 191 k and the # 3 file is almost double the size in V8. Is that normal? I am not sure what to look for next? Marc, In addition to all the good suggestions you have already received, take a look at your report for "Pass Settings". If you are not using the System Variables "Page Set with Description" option, such as [Page nn of nn], or DBCalcs with "Look Ahead" option, change the Report "Pass Setting" from "Two Pass" to "One Pass". Here's how: Report Designer | Main Menu | Report | Pass Settings This will definitely speed up the PRINT engine. Once you have made the suggested change, try the following command to PRINT the report: -- Example -- Start here PRINT NewForm76D WHERE Tr_Date BETWEEN 1/1/2009 AND .#DATE + AND InsCo1 = 7 AND CompNum = Insco1 + ORDER BY InsCo1, CustNum, Tr_Date + OPTION SCREEN|WINDOW_STATE MAXIMIZED + |ZOOM_TYPE PERCENTAGE + |ZOOMPERCENT 98 + |PREVIEW_CAPTION New Form 76D RETURN -- End here Hope that helps!
