https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=233395 --- Comment #1 from Steevan <steevanxperia@gmail.com> --- I tried contacting SuperMicro and then Intel tech support. Both suggested that the issue could be specific to FreeBSD OS. So later I tried FreeBSD 12 Beta 3 version on this server with Xeon Gold 5115 CPU. All these problems have disappeared. In this FreeBSD 12 Beta3 also contigfree takes much more time compared to contigmalloc. However when I compare the absolute values to FreeBSD 11.x number I can see huge improvement in FreeBSD 12 Beta 3. Now in FreeBSD 12 Beta3 my PCIe card driver takes just a few seconds to load and few seconds to unload. However on FreeBSD 11.x it takes 2+ minutes to load and upto 15 minutes to unload. Hence it looks like the problem is with FreeBSD 11.x. Hope the attached simple program in original bug report helps you guys to reproduce this issue.
