Created attachment 11391 [details] customer sample file The attached customer file, when run with "gswin32c 004580_ImputMix_Test_FPR.pdf" uses increasing amounts of memory as the job progresses, and also seems (subjectively) to be slower than the 9.10 release. Chris has bisected this to commit: 4e44c995bcc7a2aa6c32e23cb73fd532a93f5b1c "Fix bug 689805: Use a clist for pages with transparency that need lots of RAM"
Assigning to Ray since it seems to be clist related, and related to one of his commits.
Fixed in: http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=09def28a Note that the performance drop between 9.10 and 9.15 is mostly due to now using clists for the transparency groups - setting something like -dMaxBitmap=64m on the command line will keep performance sprightly, but prevent memory use explosions with transparency groups covering large areas.
Just pointing out that setting -dMaxBitmap=1g or larger will not always use 1 Gb of RAM, but will only use the same amount as the display device did with the code prior to the implementation of the automatic 'clist' mode for this type of device.
