SecureCRT for Mac OS X - screen refresh rate
 
First of all, let me say, I am very excited about SecureCRT for Mac OS X. I searched but could not find an option to increase the screen refresh rate. iTerm has this feature, and it makes a huge difference for me. With iTerm's refresh rate turned up, things become much smoother when running applications like top in large terminal windows. SecureCRT seems to use a lot more CPU than iTerm/Terminal when lots of input is coming its way. I was displaying a 40K line file and it took 2 minutes for SecureCRT to render it all... iTerm... 2 seconds.

Any recommendations?

thx, reverb

Hi reverb,

Thanks for the positive feedback! :)

Also thanks for the comparative data provided. Could you also provide a screenshot showing where this option is configured in iTerm?

I do not believe we currently have a configuration option that will allow you to increase the screen refresh rate.

I have added this thread to a feature request in our development database for including a config option to control screen refresh rate. Should a future release of SecureCRT include this feature, notification will be posted here.

If you prefer direct e-mail notification, contact support@vandyke.com and include "Feature Request - Forum Thread #5916" in the subject line.

Refresh rate in iTerm
 
The option is in iTerm -> Perferences

Hi reverb,

Thanks! :)

So what difference would you see if iTerm was set to the extremes on the slider, comparing Fastest/Slowest to the file you said took SecureCRT 2 minutes to render?

render times...
 
Take a 30,000 line text file for example:

> wc -l 30k.txt
30000 30k.txt

cat the file using iterm (with the slider in the middle):
> time cat 30k.txt
<snip>
real 0m0.353s

cat the file using SecureCRT w/ local session:
> time cat 30k.txt
<snip>
real 3m0.519s

Takes 3 minutes for SecureCRT to render the output from cat, which takes iTerm 0.3 seconds. Just for comparison, Mac OS X Terminal, takes 0.13 seconds. I'd expect SecureCRT to be comparable for a local terminal.

Hi reverb,

Thanks for the additional information.

I have also added this thread to a feature request in our development database for improvement to scrolling for local terminal sessions. Should a future release of SecureCRT include this feature, notification will be posted here.

To clarify, are you using a local **shell** session when performing these commands?

Or are you using an SSH session to connect to localhost?

local shell
 
Yes, using a local shell, not SSHing to localhost.
