+ <li><em><font size="3">Maximum memory limit</em><br/>
+ Since 2.11.1.0, Jalview's configuration includes a 'maximum memory limit':
+ <pre>jalview.jvmmemmax = 32G</pre>
+ Adjusting this default (via a JVL file, above) will allow larger amounts (or can limit the amount) of memory to be allocated to Jalview in conjunction with the jalview.jvmmempc setting.

+ <li><em><font size="3"><a name="jar">Command line arguments when using the executable jar (jalview-all.jar) or jalview.bin.Launcher</a></em><br/>
+ If you are using the Jalview standalone executable jar (usually named <em>jalview-all-....jar</em> with a Jalview and Java version designation) or using <em>jalview.bin.Launcher</em> to start Jalview,
+ then you can set the <em>jvmmempc</em> and <em>jvmmemmax</em> values using application command line arguments <em>--jvmmempc=PERCENT</em>
+ and <em>--jvmmemmax=MAXMEMORY</em> respectively. <em>PERCENT</em> should be an integer between 1 and 100, and MAXMEMORY should be an amount of memory in bytes, or you can append a "k", "m", "g", or "t" to use units of kilobytes, megabytes, gigabytes or terabytes, e.g.
+ <pre>java -jar jalview-all-2.11.1.0-j1.8.jar --jvmmempc=50 --jvmmemmax=20g</pre>
+ (this example will launch Jalview with a maximum heap size of the smaller of 20GB or 50% of physical memory detected).
+ <br/>The default value for jvmmempc is 90, whilst the default value for jvmmemmax is 32g if Jalview can determine a total physical memory size of the host system, and a more cautious 8g if Jalview is unable to determine a total physical memory size.
