do I need a new computer to get faster optimizations?

Since upgrading to Premium, trying to optimize thousands of permutations @ 200k has become painfully slow.
My desktop is about 8 years old (i7-3770, 3.4ghz, 8gb RAM). Would a faster processor help? or is there a bottleneck at the PRT server?03/30/2020 at 11:19 AM #12391303/30/2020 at 11:26 AM #12391503/30/2020 at 11:32 AM #123917
Maybe we should do a side by side trial (You and A. N Other etc) as to how long it takes to optimise x combinations over x bars??
I suspect it is what it is and the PRT are throttling response so we all fit in / get some bites of the cherry?03/30/2020 at 11:43 AM #123924
That would be interesting to try.
I used to just run the variables separately which is obviously much faster. Then I started noticing that you get vastly different results by running them all together, even if it takes forever.
Twice in a row I left it to run overnight and both times PRT closed down on me before I ever saw the results. 🤬🤬🤬03/30/2020 at 11:43 AM #12392503/30/2020 at 11:49 AM #12392703/30/2020 at 11:49 AM #123928

Next time turn off and on before you set it going overnight?
PRT is supposed to only switch off after 18 hours.
but i’m not so slowed in 200k and optimizations
There we are … ideal partner to do a trial with on the same optimisation … goes without saying, but though I’d say it anyway! 🙂03/30/2020 at 11:51 AM #12392903/30/2020 at 11:53 AM #123931
how long would you expect it to take? For me about 5 hours.
I know you are only getting a feel for how long, but it would be so useful if we could do a side by side trial … same System optimising on two PC’s etc.
Would be easy to set up … load up and then both say on here … START Now!? 🙂
I’m more than willing to participate, but I’ve only got 100k bars.03/30/2020 at 11:54 AM #12393203/30/2020 at 12:00 PM #123936
depends by the timeframe for sure
And I think MTF takes longer, no? as it has to run through each TF separately.
same System optimising on two PC’s
It is a cool idea, but at the mo I’ve got a long one running that I can’t possibly interrupt.
What I’m also trying that I didn’t even realise was poss, is run 2 simultaneously. They don’t seem to conflict with each other, or not much.03/30/2020 at 12:03 PM #12393903/30/2020 at 12:59 PM #123948
Since backtests/optimizations are made server side, your computer performance is not involved into any slowdown. In fact, the time to get the results of an optimization depends on many factors:

- code complexity
- iterations quantity
- Walk Forward active or not
- free available slot on servers
