Historical Market Replay slow one 1 PC but fast on another one

[music_p13]

Hello,

I have laptop - and historical market replay on continuous instruments there runs about 5 minutes of data per 1 second of real time.

On my desktop - same data runs about 2-3 hours per 1 second.

Any idea why it runs that slow on my laptop?

My laptop has processor I-7 (so does my desktop) and 12 GB or RAM...

Do I need to re-install NinjaTrader on laptop, or reset database to "Make it go faster", or why is there such a difference? Any tips/settings I should change to historical tick replay to go faster?

Thanks

Hello music_p13,

Different hardware configurations are going to be able to process different amounts of work.

Not all i7 CPUs are the same.

Are you testing with all workspaces closed in a new blank workspace with no charts?
(It may be that one computer has more workspaces or data in the workspace to process)

When running with 1 empty workspace and no charts - speed approximately 10 minutes per second. CPU usage by Ninja is around 40% - the rest of processes don't take much of CPU.

Hello music_p13,

Is the Disk usage high?

Are you testing the exact same day of data?

Thanks for help, however, solution was to re-install NT8.

Step 1 - rename existing NinjaTrader 8 folder in My Documents
Step 2 - uninstall NT8
Step 3 - install NT8
Step 4 - verify replay data works fast now with freshly re-installed NT8 with brand new folder in My Documents
Step 5 - Close NT8, - rename the new NinjaTrader 8 document, and move back the original folder from step 1.
Step 6 - Start NT8 and try replay again - now it runs about 1 hr per second on Volumetric Data (probably faster on other chart)...

So issue is solved by re-installing NT8 (haven't done it for long time, always was just upgrading NT8 - so clean install helps...).
