I updated the cache over night for one of my databases with about 900K hands, it took 4 hours, that usually takes me about 45 min.
During this update my PC froze every couple of minutes or so, to the extent that when writing on the keyboard 30 seconds of text was buffered.
When I choose that particular database (after updating the cache), I go an error message when choosing the Summary tab (see picture above), however when choosing another database that took the same amount of increased time to houskeep, I don't get a error message. I should say that I'm not sure I choose Summary for these databases with beta 24.
Also, just getting the Summary for a 900K hand database now takes "much longer" (2-3 times, estimating) than before, doesn't matter what database a choose (with or without error message). Should say I haven't timed this before and after.
This is what all my processes looked like after I updated the cache over night (the update that took 4 hours).
Not sure if this is of any interest. As I wrote before, I'm pretty sure it isn't swapping.
I guess I will get the advice to export everything and reinstall postgres, that's about 12-18 hours of work (if everything runs smoth).
It took 10 hours to install and housekeep all my databases after installing beta 24.
Think I will order that Velocity Raptor disk after all.
Edit:
I'm pretty sure "everything" started to get slow after installing beta 24 and then got really slow after installing the latest build.
