100,000 rows by 10 columns of strings up to 6 characters max uses 300mb of memory, this is 3mb per row or 300kb per item. I can understand some overhead for all the properties etc. but this seems very excessive. Using virtual mode is not an option as we require grouping. Using the global settings "UseReportCustomHeap" or "UseBatchAllocation" make no difference. Is anybody else having this problem? Is there any way of getting the memory usage down? ------------- Product: Xtreme SuitePro (ActiveX) version 17.3.0 Platform: Windows 10 / Windows 7 Language: Openedge 11.6 |

~0.003mb per row (300mb / 100000 row) 3kb per row and 300b per item |

 Thanks for the great advice  Regardless of calculations, memory usage is 300mb for 100,000 rows, this is too high, how do we reduce it?------------- Product: Xtreme SuitePro (ActiveX) version 17.3.0 Platform: Windows 10 / Windows 7 Language: Openedge 11.6 |

Use only 5 columns? 
You could show the most important columns and retrieve the others if the row is selected and show them in a details grid.
I think I also read somewhere in the CodeJock documentation not to use 100.000 rows in the report control unless you use virtual mode, because of the limitations of the grid. ------------- Product: Xtreme SuitePro (ActiveX) version 15.3.1 Platform: Windows XP (32bit) - SP 3 (on VMWare) Language: Visual Basic 6.0 |

Yeah I think we've tried to push it a bit too far, shame because it works nicely otherwise. Just thought I'd ask before giving up. Thanks ------------- Product: Xtreme SuitePro (ActiveX) version 17.3.0 Platform: Windows 10 / Windows 7 Language: Openedge 11.6 |
