Re: [rt-users] Optimising for low bandwidth
Hi Richard, not done this till now, but i think if you strip up the css this will offer you a better performance. But not sure if someone else did this already. Torsten 2008/11/7 Woody - Wild Things [EMAIL PROTECTED] Hi all, We use RT 3.8.1 (gentoo,apache2,mod perl) for use with our sales team for Safaris in Tanzania. We have extremely poor internet connectivity from Tanzania (no fibre yet) - our ISP has less transit B/W than most of you have to your homes! and 800ms latency. It is therefore important to us to keep b/w usage to a minimum. If you've every used a 14.4modem, its like that! I have a few ideas to help this and have searched the net without luck. I can code basic perl. 1. I'd like to automatically strip sigs from emails stored in the database, so the Ticket's page is not so long with all the transactions - can anyone suggest where i should put the code to do: $sig_marker= s/$sig_marker.*?$sig_marker//sg to remove a sig like my sig or should it be in a scrip? 2. I'd like to parse the transaction through something like uniq(1) to get rid of duplicate lines, and also to remove lines that are: to only one line. where should i put this code? in a scrip, or in local/lib/RT? which module? I think i can write the code, but need advice on the correct way to go about it. 3. I'd like to only display the last few emails for a ticket, and even then, maybe only the first 5-6kb of a email - our clients reply without trimming mails to relevant detail, and threads can be over 50 mails long! that can make a display ticket page over a MB in some cases. I thin this may be a larger hack. 4. If anyone else has any great ideas about how to optimise RT for low bandwidth, I'd love to know! thanks in advance Woody. -- --- Richard Wood (Woody) Managing Director Wild Thing Safaris Ltd.
