[Piwik-hackers] Fatal error: Maximum execution time of XXX seconds exceeded

[Patrick Joyce]

Last night I began to get "Fatal error: Maximum execution time of 30
seconds exceeded" errors when executing "Referers.getKeywords" for the
period "last30".

I first updated to the head of the trunk (r546) and this made no
difference. I had installed and was previously running r521.

I increased the maximum execution time to as high as 600 seconds to no
avail. All the other API calls I do still work, and
Referrers.getKeywords still works in under 60 seconds for periods of
"last7", "last14", and "last21"

"last28" times out at 600 seconds. Can the addition of 7 more days
really result in a 10 fold increase in execution time?

My install has about 20 different sites, 10 of which are active and is
only processing about 100 visits a day.

Any ideas on how to speed up execution?

Thanks in advance for your help,

Patrick Joyce
