Extreme slow transaction registers (Q Windows under Parallels on a Mac)

mtbdog

Entering transactions of any type in any register taking 10-15 seconds before I can enter another or switch to another task. This is an older data file that is quite large, 308 mb. Another file (doing my mother's bookeeping) is newer and much smaller. Transactions are almost instantaneous in that file.

Quicken Classic Premier v. 64.35

Win11 running in Parallels VM on Mac Mini M4.

Data file is on local SSD drive, not in OneDrive or iCloud.

Any new ideas about this?

Hello @mtbdog,

Thanks for the detailed breakdown—the file size and age definitely stand out as factors here. Performance slowdowns like this are often related to file data integrity (especially in long-running investment registers), even when the file is stored locally and the system specs are solid.

Please take a moment review this support article. It covers key areas to review and walks through creating a file copy and validating it, which can help identify or repair data issues that build up over time in larger files:

Since you mentioned the slowness only occurs in the older / larger file — not the newer one — the Copy & Validate portion of that article is the most relevant next step to check for data integrity issues or damaged lots.

Hope this helps!
