I really hope you allocated only that much of RAM, not your PC having only 192MB RAM even being a dual core system. <img src="/styles/default/xenforo/smilies/default/lol.gif"  class="smilie" loading="lazy" alt=":lol:" title="LOL    :lol:" data-shortname=":lol:" /> Expanding upon what you did, I tested winzip winrar and 7zip for a double kick to Ranga.The Computer:<img src="http://img256.imageshack.us/img256/6544/syspropertiesfx8.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Note: All programs are 32bit to even the playground.Test 1The folder size is 300MB, contains five video files (.wmv)<img src="http://img256.imageshack.us/img256/4815/test1lk8.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />7Zip: <a href="http://www.egoshare.com/57c025aef993744314313ca7693da730/7zip1wmv.html" target="_blank">http://www.egoshare.com/57c025aef993744314313ca7693da730/7zip1wmv.html</a> (7zip takes 30sec)WinZip : <a href="http://www.egoshare.com/c5dec704e998e61f75d2f0f27c51ec8d/winzip1wmv.html" target="_blank">http://www.egoshare.com/c5dec704e998e61f75d2f0f27c51ec8d/winzip1wmv.html</a> (winzip takes 40 sec for legacy zip)WinRar : <a href="http://www.egoshare.com/847815e8c64c1540639e43f95e7aa597/winrar1wmv.html" target="_blank">http://www.egoshare.com/847815e8c64c1540639e43f95e7aa597/winrar1wmv.html</a> (1min video winrar processed 40%)Interesting observation: 7zip compresses zip faster than winzip when doing these videos (10sec difference)Test 2The folder size is again 300MB, contains assorted pdfs docs and jpgs<img src="http://img380.imageshack.us/img380/8871/test2mn7.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />7Zip : <a href="http://www.egoshare.com/dc58139d111d962dfb4ecf17c131a5ad/7zip2wmv.html" target="_blank">http://www.egoshare.com/dc58139d111d962dfb4ecf17c131a5ad/7zip2wmv.html</a> (41sec)WinZip : <a href="http://www.egoshare.com/9b276c0445ea1d3e38e05e552d30021e/winzip2wmv.html" target="_blank">http://www.egoshare.com/9b276c0445ea1d3e38e05e552d30021e/winzip2wmv.html</a> (about 39sec again legacy zip)WinRar :  <a href="http://www.egoshare.com/549bf6b8855b589d9a9a52535808d490/winrar2wmv.html" target="_blank">http://www.egoshare.com/549bf6b8855b589d9a9a52535808d490/winrar2wmv.html</a> (1min video winrar processed 33%)Compressing these assorted files WinZip seems to be on par or better by 2secs.winrar seems to need atleast 5 times(I'm being generous in estimating poor winrar) more time than 7zip to do a compression job. That's similar to your observation of winrar being 6 times slower than 7zip <img src="/styles/default/xenforo/smilies/default/D.gif"  class="smilie" loading="lazy" alt=":D" title="Big grin    :D" data-shortname=":D" />The interesting thing is 7zip is on par with winzip, or sometimes faster than winzip when doing zip format <img src="/styles/default/xenforo/smilies/default/happy.gif"  class="smilie" loading="lazy" alt=":)" title="Happy    :)" data-shortname=":)" /> No need to talk about winrar. <img src="/styles/default/xenforo/smilies/default/lol.gif"  class="smilie" loading="lazy" alt=":lol:" title="LOL    :lol:" data-shortname=":lol:" />Now Ranga, the ball is in your park <img src="/styles/default/xenforo/smilies/default/lol.gif"  class="smilie" loading="lazy" alt=":lol:" title="LOL    :lol:" data-shortname=":lol:" /> Give us some statistics of your winrar.Statistics mean benchmarks not things such as this:winrar: used by zillions7zip: used by negative infinitylol your lovely purple color <img src="/styles/default/xenforo/smilies/default/lol.gif"  class="smilie" loading="lazy" alt=":lol:" title="LOL    :lol:" data-shortname=":lol:" /></blockquote>
