server performance tuning

[leahyj]

Hi,

I have a couple of related questions, one more specific and the other less specific.

Less Specific:

Does anyone change the default settings of IIS 6.0 to improve ASP performance?

More Specific:

I am pulling an image from an Access database ole object field and displaying it on the screen using this method, "Response.BinaryWrite oRs("olepic1").GetChunk(oRs("olepic1").ActualSize)"

Is there a way to manipulate the byte size of the jpeg before it displays, so that it displays faster?

Thanks

Do you mean other than just resizing the image or increasing the compression on the jpeg?

You could try setting up a loop that gets smaller chunks instead of the entire thing at once, writing out the smaller chunks and doing a response.flush inside the loop... i doubt this would make much difference though unless the images are really quite large.

Sheco,

I like the first suggestion.

How do I go about increasing the compression of the jpeg?

Thanks.

If you open up your JPEG in an image editing software (example:The Gimp) you should be able to set the compression level when you go to save it.

If it were me I would fiddle around with this and see how much I could increase the compression before the image quality goes down the tube. Then I would look for an ActiveX/COM object that could do the compression and write a little VBS file that goes along and compresses all my existing images. Finally I would investigate ideas for compressing new images as they are added to my database.
