Hi Marcel, wget1.x can only download one file at a time. Of course you can use multiple instances in parallel.
Wget2 uses 5 parallel threads per default (can be tuned with --max-threads=N), so no need for parallel instances. If you give e.g. 5 or less URLs, they are downloaded in parallel without the need for tuning. Here comes a little complication... HTTP/2 behaves slightly different than HTTP/1.1 as it allows parallel requests (streams) on one connection - if all URLs have the same domain. Next, Wget2 has a stats module that allows to generate one data record per URL including timings (millisecond precision), see --stats-site. In the Wget2 repository are also some benchmark scripts in subdir benchmarks/. Example: $ wget2 --stats-site=csv:- www.gnu.org www.heise.de www.oracle.de ... ID,ParentID,URL,Status,Link,Method,Size,SizeDecompressed,TransferTime,ResponseTime,Encoding,Verification,Last-Modified,Content-Type 1,0,http://www.gnu.org,200,1,1,9168,28592,235,234,1,0,0,text/html 2,0,https://www.heise.de,200,1,1,58158,434935,53,27,1,0,1568496351,text/html 3,0,http://www.oracle.de,301,1,1,217,270,341,341,1,0,0,text/html 4,0,http://www.oracle.com/de/index.html,301,0,1,0,0,180,180,0,0,0,(null) 5,0,https://www.oracle.com/de/index.html,200,0,1,8511,32215,160,160,1,0,1568450074,text/html It also records the redirections as you can see. See docs/wget2.md for more info regarding the fields.
