[rt-users] Optimising for low bandwidth
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.

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.
