Interesting (i have one laying around). Did you use a 'real disk' or the
small card?
When using the cache, I usually clear it first and then run the script
several times. I also obey xosview in order to make sure that no
other processes interfere. I think that an empty cache is what you
have after a fresh startup. And the most important thing is that no
web-browser is running when doing benchmarks.
Indeed, and no thunderbird either -)
Hmm, something similar is Taco's string.explode() function. It's much
faster than regular expressions, so I prefer it. What I didn't
Right, The reason for introducing string.explode is simple splitting.
Sure. But as far as I can see it doesn't hurt. The table is
overwritten whenever a new chunk is processed. Thus, things don't
accumulate. I don't know what happens when I overwrite a table.
But you still store the data twice (and I thought that you wanted to
limit mem consumption)
Maybe the new one allocates new memory and the old one is left to the
garbage collector. But if this is the case, then the garbage
collector does a pretty good job. The function is very fast and
memory cunsumption isn't even visible in xosview.
it sometimes helps to do a sweep: collectgarbage("collect"), you could
play with doing that after (say) every 5 buffer loads
BTW, the f:read(BUFFER, '*line') concept can be less efficient if lines
are extremely long...
inefficient anyway, just as the 'lines' method
Well, it splits the file though:
string.gmatch(buffer,"([^\n\r]-)(\r?\n)")
I suppose that the most promising approach is to use regexps in order
to determine the linebreak style, abort, and read the file again using
Taco's function.
yes, that sounds best (you could look at the last few characters of the
file, assuming that the log files ends each line with a newline)
Anyway, our discussion is obviously off-topic here. Hans, I'll inform
you about the results by private mail. If anybody else is interested
in the results, just drop me a line.
Ok.
Hans
