    Max Query Join

    Your perseverance has paid off CJ, not all the fields were indexed. Initial form loading takes approx. 2 secs and thereafter, it's pretty much instantaneous. Brilliant, massive thanks 👏 @tvanstiphout - I should've checked other fields after you also mentioned indexing earlier in the thread 👍

    Max Query Join

    Previously, the amount of data was since the last archive (start of 2022). I've whittled it down to 180 days as per above suggestion and although it's not ideal (approx 7 seconds), it is a bit more palatable until the hardware is upgraded. Thanks CJ

    Max Query Join

    I give it a try - if I run the first query in the background, in theory it should pull in the second query more quickly. Perhaps an issue with Windows 8 or slower PC spec all round

    Max Query Join

    Data is usually on a network but it doesn't appear to be a contributing factor - placing the backend on the desktop doesn't make a difference. Removed order by and it reduced by approximately 2 seconds, good shout but performance remains very poor on this particular aspect

    The slow PC is on a network but the speed doesn't improve when both the front and back end are moved to the desktop

    Max Query Join

    1. Yes, Autonumber 2. Both queries based on same table, yes it has PK 3. See 1 4. It is now, took it down to approx 18 seconds, thanks 5. 8 year old PC, 8 GB RAM running on Windows 8.1 - I should've included in my original post that it works within a second on another PC, apologies.

    Max Query Join

    Hi, I've got an issue with a slow query. I'm using the MAX function in an initial query (detailed below) to obtain the highest VisitorSignInID - typically this completes within a second. Upon running the second query below to pull in additional field values from the underlying table with...
