How do I increase cache size in Chrome?

Absolutely. An easy fix to this is to add the following argument to the command.

chromium-browser --disk-cache-size=n

say n is 500000000 this would be 500 MB

You can check to make sure it increased it by typing the following in your browser and then looking at the Max Size value.

chrome://net-internals/#httpCache

Start chrome with the following option:

--disk-cache-size=n

Where n is the cache size limit in bytes.

Chrome now has two startup switches that you can use --disk-cache-dir and --disk-cache-size.

Simply close Chrome, right-click your Chrome shortcut, click Properties, and then in the field labeled "Target:", make it look something like this:

"...chrome.exe" --disk-cache-dir="CACHE_DIR" --disk-cache-size=N

Where CACHE_DIR is the new cache location, and N is the cache size limit, in bytes.

Use whichever switch you need, or both. Keep in mind, however, that these features may not be completely stable yet. But you probably shouldn't have any problem with using them.

And to anyone who's interested, I caught gander of the existence of these switches directly from a source code file for Chrome.
