How to run multiple instances of Writer simultaneously?

[Jens Tröger]

Thanks Matthew,

What I need is "bulk processing" of documents. I currently run LO in headless mode and open the documents in read-only format (macros disabled) hoping that would improve performance. To answer to your points: no interactiveness and high throughput to scrape document content.

Your suggestion of running a pool of LO instances seems to be implemented by the oodaemon (https://sourceforge.net/projects/oodaemon/) that I mentioned earlier, but the project seems quite dated.

Cheers,
Jens

(i.e. is it an interactive process that will primarily require low latency, a bulk process that requires high overall throughput but may not mind if individual requests are delayed for a short time, or something that requires both low request latency and high throughput?)

There is definitely no canned answer for this, so you would have to do your own benchmarking and tuning to find the optimum pool size for the resources of your local machine.
