Subject [jira] [Commented] (TIKA-2180) Multiple requests on Tika to extract text slows down

Ashish Basran commented on TIKA-2180:
-------------------------------------

I tried with new experimental parser and with this document memory usage reaches it's limits.


I also tried with same document converted to PDF and see the same issue with memory utilization.
I tried with other set of different type of documents (.csv, .doc, .htm, .pdf, .msg, .ppt,
.xlsx etc) and memory usage was under 1 GB. My observation with .docx, .xlsx, .pdf is that
process is not releasing memory. It keep using to whatever peek it reaches.

> I observed that if I send multiple requests to Tika (eg. http://localhost:8080/tika)
with around 5MB files, Tika is very slow in completing the action. I tried with ~20 random
files, it took 170 seconds to process all the files in sequence. If I pass all files in parallel,
it took around 780 seconds to process same set of files.
