#24 Sorting tags alphabetically lasts very long

[StefanD]

Hi,
my Test-Installation is running on a shared host. I noticed gradually that the time needed for sorting the tags by alphabet is rising with the number of tags. When I reach a number of more than 1.500 tags the sorting lasts more than 30 seconds which results in a error message:

XML Parsing Error: junk after document element
Location: http://semanticscuttle.example.com/alltags.php/admin?sort=alphabet_asc
Line Number 2, Column 1:Fatal error: Maximum execution time of 30 seconds exceeded in /path/to/semanticscuttle/src/SemanticScuttle/utf8.php on line 168

Because it's a shared host I have no opportunity to increase the execution time for php-scripts :(
And I wonder why this error occurs in utf8.php and not (for example) in alltags.php?

Is there a possibility to sort tags alphabetically by default (and with an option in config.php to order them by popularity instead)?
Or is there a chance to increase the speed for the sorting process by alphabet? Sorting the tags back by popularity lasts at least only one or two seconds...!

Thanks for your help
Stefan
