I’ve no thought the place to place this.  I am not pc technical.

Intel© Core™ i7-8700K CPU @ 3.70GHz × 6cores     This has 12 CPU exhibiting in system settings dialogue.   I run spreadsheet (massive ones).  It doesn’t matter what I do they at all times appear to be operating only one CPU at 100% and the remaining barely do any factor simply operating at round 1 to 2% typically will go as much as 4 to eight% in one other CPU.

You see from picture that system monitor reveals varied readings however when the spreadsheet is operating alone it’s as I acknowledged above.  All these CPU’s and just one is maxed out.  Spreadsheet gradual (i.e. 20 minutes to save lots of after modifying).  Reminiscence utilization appears to be caught at 5 to six Gig

Is there one thing I can do about this to make the pc /Intel chip to make use of much more of the sources obtainable ??

The screenshots have loaded with 2nd picture first – I’ve simply began spreadsheet inserting a brand new clean column into columns already in spreadsheet.  third picture is identical as 2nd picture however barely additional on within the column insertion course of.

So saving takes ages and in addition modifying as defined above

This spreadsheet has 30000 rows and 140 columns.
