REQ Dual \ Quad Core Support

Post by ckit »

XnView needs Multithreading support for dual-core and quad-core CPU's!
Also making use of SSE,SSE2 and SSE3 if they available would be nice too!!

I'm hoping XnView 2.0 will have multi-threading for All batch operations, the rest of XnView won't benefit from multi-threading unless you're resizing really massive resolutions :)

Mmh, just did a conversion job here and XnView (1.95.4) just made use of one core :(


Would be great if we could specify number of threads in the preferences so that XnView could convert say 4 images at the same time on a quadcore ...

Sorry but I disagree. Stepping through my 6MP photos on a Core2Duo E6600 could be much faster if the image/jpg loading mechanism would use several cores.
AFAIR JPG would be the perfect candidate for a multi core loading as each jpeg block is independent of the others. Therefore the image could be divided easily into 2/4/8 parts which could be then loaded in parallel.
