Is there any way to keep a daemon load time at under 10 mins when there is site related wallet issues etc?
...
With the 100 thousand addresses you tried what was the daemon boot up time?
The time became a factor when the oldest address is very old (used in 2012 or 2013), or if the wallet has plenty of transactions. Took anywhere between 20 to 30 minutes, maybe 40. But I am using a HDD on a laptop. I'm on a spinner, not solid state.
If you create a new wallet today, the load time even with a rescan is quite short.
That's the key, it's the load or rescan time that takes time. When the wallet is running, it works fine.
A way to keep load time low is to use SSDs, or as I have stated in another thread, to store the whole thing in RAM. Get 128 GB of RAM and create a RAM drive. Use an old server (5 year old off-lease servers with that much RAM can be bought for $600 USD).
Or use a bunch of SSDs (maybe 8 to 12, or more) and run them all RAID 0 (zero).
