drupal 8 static content not generated

[gopedib]

Hi, I am using this oss-framework and have been able to run and get rps numbers for wordpress, mediawiki and drupal7 with no major issues. But for this drupal 8 (no-cache and page-cache both) I am not being able to generate static contents. I tried couple of things such as changing the r/w access to files directory using "shell_exec('chmod -R a+wr sites/default/files')" from Drupal8Target.php file, as people in drupal8 forum suggested. Apparently I do not see why hhvm with this --file-cache option not being able to generate static contents for drupal8. Any suggestions/patches for that? I have been trying to make it run for 2/3 days but with no success.

hhvm perf.php --apply-patches=true --i-am-not-benchmarking --drupal8-no-cache --hhvm=/home/dibakar/hhvm_orig/hhvm/hphp/hhvm/hhvm --siege=./siege-2.78/bin/siege

hhvm master no longer targets PHP5; this should be entirely removed, in favor of #84
