Re: Performans of left.pl

Hi Mike,

You might try cd'ing to ui and running (twice) on an unloaded system:

time left.pl

This will give you an idea of how long it takes just to load and parse Perl and the Perl modules. If you repeat this command, then the % time used by the second try should be near 100%. If it is near 100%, and it takes 5 seconds, then you're out of luck and you need a faster server. If it is substantially less than 100%, then you are probably running into some I/O bottleneck -- perhaps you are accessing some part of LAS (Perl, Perl modules, MySQL, etc.) over a slow network. Or, your system is loaded down with other processes, or doesn't have enough memory, etc.

LAS v6 is much faster, since it uses Java servlets instead of CGI (doesn't have to fork a process and parse a bunch of Perl modules with every access).

Hello LAS users/developers,

I have 12 data sets each with 17-19 variables.  On my local intranet it
takes about 5 seconds to open the variable list from a different data set.
Is there any way to speed this up?  (Maybe I just need a faster server.)

I remember that with an earlier version of LAS (maybe 3.0) that all the
variable lists were downloaded to the client and available more quickly
through some JavaScript.  Is this still a possible option?

Also, I think that if the 'width="100%"' was removed in the Dataset
description table then all the dataset names will align better.
