libreoffice takes around 40 seconds to start on my core i7 laptop. Judging by ktrace, what it does is reading iosevka fonts. This fragment:

```
 56210 soffice.bin CALL  openat(AT_FDCWD,0x898551f08,0<O_RDONLY>)
 56210 soffice.bin NAMI  "/usr/local/share/fonts/Iosevka/iosevka.ttc"
 56210 soffice.bin RET   openat 24/0x18
 56210 soffice.bin CALL  fstat(0x18,0x821158f60)
 56210 soffice.bin STRU  struct stat {dev=6602381364165455651, ino=853229, mode=0100644, nlink=1, uid=0, gid=0, rdev=18446744073709551615, atime=1700500430.680679000, mtime=1700500431.123096000, ctime=1700500463.811403000, birthtime=1700500431.123096000, size=261945172, blksize=131072, blocks=205593, flags=0x800 }
 56210 soffice.bin RET   fstat 0
 56210 soffice.bin CALL  mmap(0,0xf9cf754,0x1<PROT_READ>,0x1<MAP_SHARED>,0x18,0)
 56210 soffice.bin RET   mmap 38558236672/0x8fa400000
 56210 soffice.bin CALL  close(0x18)
 56210 soffice.bin RET   close 0
 56210 soffice.bin CALL  munmap(0x8fa400000,0xf9cf754)
 56210 soffice.bin RET   munmap 0
```

Repeats up to 26568 times for each iosevka .ttc file:

```

Workaround to fix the slow startup is thus to remove iosevka font.

I think it should be reported upstream, just leaving it here for searchability and for the workaround.

I've filed upstream bug report: https://bugs.documentfoundation.org/show_bug.cgi?id=158287
I've also found Gentoo report of the similar problem: https://forums.gentoo.org/viewtopic-p-8807829.html
And here's full kdump output just for the case: https://people.freebsd.org/~amdmi3/libreoffice.ktrace.txt.xz
