 \fBSYNAPSE_CACHE_FACTOR\fR
-Synapse\'s architecture is quite RAM hungry currently \- a lot of recent room data and metadata is deliberately cached in RAM in order to speed up common requests\. This will be improved in future, but for now the easiest way to either reduce the RAM usage (at the risk of slowing things down) is to set the SYNAPSE_CACHE_FACTOR environment variable\. Roughly speaking, a SYNAPSE_CACHE_FACTOR of 1\.0 will max out at around 3\-4GB of resident memory \- this is what we currently run the matrix\.org on\. The default setting is currently 0\.1, which is probably around a ~700MB footprint\. You can dial it down further to 0\.02 if desired, which targets roughly ~512MB\. Conversely you can dial it up if you need performance for lots of users and have a box with a lot of RAM\.
+Synapse\'s architecture is quite RAM hungry currently \- we deliberately cache a lot of recent room data and metadata in RAM in order to speed up common requests\. We\'ll improve this in the future, but for now the easiest way to either reduce the RAM usage (at the risk of slowing things down) is to set the almost\-undocumented \fBSYNAPSE_CACHE_FACTOR\fR environment variable\. The default is 0\.5, which can be decreased to reduce RAM usage in memory constrained enviroments, or increased if performance starts to degrade\.
-.
+.IP
+However, degraded performance due to a low cache factor, common on machines with slow disks, often leads to explosions in memory use due backlogged requests\. In this case, reducing the cache factor will make things worse\. Instead, try increasing it drastically\. 2\.0 is a good starting value\.
