Just for fun... :P

Work in progress, don't use for anything serious! And note how competitive the CRT strstr() algo is, at least for one byte patterns :biggrin:

It needs a 4MB text file, which gets automatically downloaded if it's not in the exe's folder.

Really fat differences between two i5 CPUs again ::)

Thanks to everybody :icon14:

P.S.: Dave... :eusa_naughty:

I use that 4 MB text file for rather pragmatic reasons: It is difficult to find a text corpus for such tests that is large enough to go well beyond the data cache. Sometimes I concatenate it to do the tests with 400 or 800 MB, which is close to the allocation limit of Windows.

Can test that with strstr from pocrt.dll too?

Here it is - note that in order to see Pelles C results, pocrt.dll must be in the path:

Line counts differ in this version:
Code Select
578 ms  for finding 42665 lines containing [therefore] using CRT strstr()
183 ms  for finding 65296 lines containing [therefore] using faster Instr_()

The reason is that the new algo has the IntelliSense option, as in MasmBasic Instr_(). It allows to search for e.g. "therefore" as in the test run above, and to catch Therefore and therefore (but not tHereFore etc). This is evidently an important option for text searches.
