povbot/svn/commits: * alga committed revision 4931:20:52
povbot/svn/commits: Optimizing recurrent events.  Daily and Yearly are done, as is one case of monthly recurrences.  Weekly and Monthly by weekday still to come.20:52
th1aalga: What kind of speed improvements are you seeing?20:53
algahard to say :-)20:53
algathe other approach (caching) gave a 30 times improvement20:54
algafor daily recurrent events seen several years in the future20:54
algamy current approach is even better20:54
th1aOK.  So very large improvements.20:55
algawell, the problem was that the recurrences were recalculated each time for all those years20:55
algawhich amounts in lots of adding dates :-)20:55
th1aSo the first time you look ahead you still take a hit?20:55
alganow I just jump to a recurrence close to the interval we're interested in20:56
algaalso, with the caching approach there was no hit on the first view20:57
th1aIs it a persistent cache or in memory?20:57
algabecause all the events are touched many times when rendering a yearly/monthly calendar view20:58
algajust inefficient architecture20:58
algawe were thinging of persistent cache20:58
algahaving a "savepoint" every 20 recurrences or so20:58
algaand calculating them from the closest one20:58
algabut then we figured out that we can calculate the closest one procedurally20:59
algaor, er, functionally...20:59
algaso, now jumping several years to the future does not require enumerating all those recurrences in between21:00
algathere is a lot of stupid code in the view21:00
algaignas was especially unhappy with how the all day events were integrated21:00
algaperformance wise21:00
algabasically, they doubled the rendering time of the calendar views21:01
th1aOof.  Well, at least there is room for improvement.21:01
th1aWe do need to finish the proposal/time estimates for this work.21:01
algaI'll take on this once I'm done with my current task21:02
th1aI sent an update to yesterday.21:02
*** th1a is now known as th1a|way21:03
algaAlso, I'm planning to take a week off next week21:03
