EFS Performance Issue

[cpatte7372]

Hello,

I have recently been working with the attached efs. Whenever I attach the efs to a chart it severly slows down the time it takes to move from the 30min time interval to the daily interval. I know its this efs because when I remove it moving from one time interval to another is much quicker.

I was wondering if someone would be kind enough to just check it out and let me know if there is anything I can do to fix it.

Thanks a lot.

Cheers

The best first step would be to comment out the debugPrintln statement.

Hi David,

I have just commented out the statement, unfortunately it still takes forever - even when refreshing the screen it takes an inordinate amount of time.

Ok, I assume you reloaded the fs.

Try

var Vol = volume()

[cpatte7372]

Yes, I reloaded the fs.

Should I place the statement you mentioned within the main function? Or above it?

Thanks

Carlton,

Dave nailed your problem IMHO, just to add, here is some history on how debugPrintln can adversly affect performance ==>> in this link

The statement replaces the similar statement on line 19

Beautiful,

Its working fine now.

Once again you guys have come up trumps.

David,

Just a quick question. By replacing line 19 with var Vol = volume(), what have I achieved?

Carlton

[dloomis]

As I recall, getValue functions are slow, and volume() is fast.

You have replaced a slow function with a fast one.

David,

That was a silly question - I know what I have achieved. I guess what I'm trying to say without sounding negatively is "have I somehow reduced the effectiveness of the efs now that I have replaced line 19"?

David,

It turns out I didn't reload the fs properly after commenting out the debug statement.

Commenting out the debug statement was all I needed to do.

Thanks again guys.
