Checking memory allocation

After updating your memory settings you can verify the changes have taken affect by going to ‘Help > Debug’ and looking at the ‘Memory’ line.

The SEO Spider will allocate 2gb of RAM by default, so you the line will look something like this:

Memory: Physical=16.0GB, Used=170MB, Free=85MB, Total=256MB, Max=2048MB, Using 8%

The Max figure will always be a little less than the amount allocated. Allocating 4GB will look like this:

In this case ‘Max=4096MB’ indicates that 4gb of RAM has been correctly allocated.

Please note, the figures shown here aren’t exact as the VM overhead varies between Operating system and Java version.

Troubleshooting

• Check that C:\Program Files (x86)\Screaming Frog SEO Spider\ScreamingFrogSEOSpider.l4j.ini doesn’t have an extra -Xmx line in it.
• If changing memory settings has no effect on this output please check you don’t have a _JAVA_OPTS environment variable set.
