Resizing of images with ResampleOp.filter slow on WebSphere 8.5.5 about twelvemonkeys

Hi Igor,

I have looked into this issue a little, and I thought I had implemented a faster (but less accurate) sin method (using lookup), but then testing showed it was slower.. So I'm a little confused about that.

But maybe it wasn't the problem after all?

Note that there are other filters available than the Laczos, that might provide good enough results, in less time.

Would it be possible for you to post the actual JProfiler data (not a screen shot), to allow me to dig a little more?

Regards,

Unfortunatelly, I have not saved the files. But I will try to perform test again today and post you the profile data

I'll close this one as non-reproducible for now.

Should you find the time to profile and figure out what's making the bad performance, feel free to reopen! :-)

Thanks,

Harald K

Sorry for late response. My trial period for JProfiler has expired, I will look into obtaining the license for it, and perform tests again.
