Interesting considerations. Whatever the causes, LC 9 needs a little
work to get back in shape. Get off the couch and start running again! :)
There are so many different tasks where 9 is underperforming; any code
with repeat loops, chunks, arrays, or math is likely to be slow compared
to where we were 2 years ago. Mac is affected just as badly as Windows.
Linux is affected too.
BTW Bob, Mark, Jerry, and others following this thread - could you also
add your CC to the bug report in the QA center?
https://quality.livecode.com/show_bug.cgi?id=21561
We need to get this problem squared away so that our LC code can
accomplish greater things, and nothing says "it's important, it's pretty
urgent" like more emails in the CC list.
Anyone with more than a few lines of code is likely to benefit from this
effort. Any serious code written in LCS, especially any code for working
with data or calculations. Do you want your own code (and the extensions
you use) to run faster or slower - if you like your code to be in shape
and run a decent mile, please take a moment to join this bug report.
And if anyone has sample code that hints at more (or more specific)
problem areas to help pinpoint the issues, don't be shy! I believe a
number of areas are affected, but who knows, maybe the root cause could
be the same.
Working on a WordLib update during the last few weeks has given me a
good opportunity to observe the slowdown, because WordLib supports both
LC 6 and 9, and it also requires thousands of tests with hundreds of
documents to test fixes and ensure quality.
So I measure speed too while I'm at it. Testing various code changes, I
could see there are many coding tasks that LC 6 absolutely loves, even
speeding up, while 9 just slows down. I ran into more potential problem
areas that need to be isolated into test code once I sort them out, but
may not get a chance to do so for a little while. Plus I may be missing
something important. So if you have sample code that tests something I
haven't, please post it. Thanks.
(WordLib release will be out soon!)
