I'm seeing the same with Solr 5.1.0 after upgrading from 4.10.2. Here
are my timings:
4.10.2:
process: 1432.0
highlight: 723.0
5.1.0:
process: 9570.0
highlight: 8790.0
schema.xml and solrconfig.xml are available at
https://github.com/NatLibFi/NDL-VuFind-Solr/tree/master/vufind/biblio/conf.
A couple of jstack outputs taken when the query was executing are
available at http://pastebin.com/eJrEy2Wb
Any suggestions would be appreciated. Or would it make sense to just
file a JIRA issue?

Short form:
While testing Solr 5.0.0 within our staging environment, I noticed that
highlight enabled queries are much slower than I saw with 4.10. Are
there any obvious reasons why this might be the case? As far as I can
tell, nothing has changed with the default highlight search component or
its parameters.
A little more detail:
The bulk of the collection config set was stolen from the basic 4.X
example config set. I changed my schema.xml and solrconfig.xml just
enough to get 5.0 to create a new collection (removed non-trie fields,
some other deprecated response handler definitions, etc). I can provide
my version of the solr.HighlightComponent config, but it is identical to
the sample_techproducts_configs example in 5.0. Are there any other
config files I could provide that might be useful?
Number on “much slower”:
I indexed a very small subset of my data into the new collection and
used the /select interface to do a simple debug query. Solr 4.10 gives
the following pertinent info:
"response": { "numFound": 72628,
...
"debug": {
"timing": { "time": 95, "process": { "time": 94, "query": { "time": 6 },
"highlight": { "time": 84 }, "debug": { "time": 4 } }
---------------------------
Whereas solr 5.0 is:
"response": { "numFound": 1093,
...
"debug": {
"timing": { "time": 6551, "process": { "time": 6549, "query": { "time":
0 }, "highlight": { "time": 6524 }, "debug": { "time": 25 }
