One quick improvement can be to add add -Xm*s*6144m along with -Xmx6144m this causes jvm to acquire all memory before hand and it would not waste time in allocating more memory by requesting to kernel.
On restart, I am not sure but I guess solr does some syncing of indexes, so it might be slow to respond in that duration.
