scala - akka performance on linux with compilation on windows -


i have scala ide setup in windows machine. when run test program on same machine performance figures.

in order run same program on linux machine, 8 core 32 gb machine, ftped generated class files , scala + akka jars linux machine.

the linux machine using server edition java , windows machine using client edition java.

when run same program on linux machine paths set properly, poor performance windows machine.

why so? program able run fine performs poorly on higher-end machine , on server edition.

is due compilation , run environment differences? can investigate reason behavior.

edit: windows env compilation done 32 bit, , java on linux machine 64 bit server. make difference performance?

it helpful if post java configurations on both machines, i.e. jvm version , flags passed java command on both environments.

also, how measure performance, , values get? there else involved, such i/o, network traffic etc.? if not, algorithms being used in program? program calculates , terminates, or server program runs until shut down?

you should put special focus on memory configuration (as suggested @alex23) , -server flag. also, make sure linux environment using jvm same manufacturer windows environment. windows typically comes sun jvm, whereas linuxes may still have old oracle jvm. try java -version on command line.

also, instead of comparing results of complex program, try simpler program first. try determine overhead of booting jvm, versus effective runtime of java/scala code.

the idea windows-based build causes performance issues on linux machine sounds highly improbable. can check compiling software on linux machine , running it.

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
