Another factor is a benchmark, it is quite aggressive. On real applications numbers usually 2-3 times lower.<br /><br />BTW you can run benchmark on your hardware.<br />Just read instruction on github (link in article). It will calculate and report average GC pause itself (not need for log scrapping).Alexey Ragozinhttps://www.blogger.com/profile/13720493857045012756noreply@blogger.comtag:blogger.com,1999:blog-7735872642513631302.post-22666117306751115042013-08-01T10:33:04.153+01:002013-08-01T10:33:04.153+01:00Could you elaborate, what 10?Could you elaborate, what 10?Alexey Ragozinhttps://www.blogger.com/profile/13720493857045012756noreply@blogger.comtag:blogger.com,1999:blog-7735872642513631302.post-26106714374479255432013-07-31T19:55:42.152+01:002013-07-31T19:55:42.152+01:00I think the scale is 10 to high ?
